Hello,

Thank you for reaching out and I am happy to assist you with this.
Can you please share which testing tools you used to test the performance and what configuration you used in the W3 Total Cache?
I can see that W3TC is not enabled at the moment. Can you please confirm this?
Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
This depends on which settings you have enabled in W3 Total Cache General settings. However, since the issue is with image loading on a pop-up, most likely it’s related to the Lazyload option.
Can you please go to Perfrormance>General settings, scroll down to the User Experience section and disable Lazyload option, save all settings and purge the cache and see if the problem persists?
Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
This depends on which settings you have enabled in the W3 Total Cache. I’ve tried to check the website, however, it’s in maintenance mode, and I am guessing that the W3 Total Cache is not enabled.

Can you please disable the settings one by one in Performance>general settings, save the settings and purge the cache after each setting is disabled, and see which one might be causing the issue? Please start with the Lazyload as this is the most obvious if it’s enabled of course.
If the Lazyload is causing the problem, it means that elementor is using some kind of lazyload for those pop-ups, and you should exclude this image from being lazyloaded by adding the URL in the Performance>User Experience>Exclude words: field. Make sure to save all settings and purge the cache once you add the image to the exclusion list.

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
Can you please share if the Object Caching is enabled in W3 Total Cache and if so which caching method you are using for Object Caching?
Have you also checked with the WPML if those queries are deliberately prevented from being cached?
Thanks!

Hello Trevor,

Thank you for reaching out and I am happy to assist you with the Image service option in W3 Total Cache.
As I can see while checking your websites, some images are converted and being served as webp, the others are not.

Can you please confirm if you converted all the images or only some images and can you share an example of the image URL that you converted and it’s now showing as webp?
Thanks!

Hello Slaveya,

Thank you for reaching out and I am happy to assist you with this.
This means that the minified CSS needs to be rebuilt or the cache needs to be purged once the content is charged/edited.
I am not seeing the minify enabled now checking the website you shared, however, if the issue is gone when Minify is enabled, re-enable minify, and disable the settings in Performance>minify one by one (HTML minify, JS minify, CSS minify) and see which one might be causing the issue.
Make sure to save all settings and purge the cache after each option is disabled.
The code is not lost and W3 Total Cache does not remove any of the original CSS or JS, it only minifies the assets.
Thanks!

Hello Thomas,

Thank you for reaching out.
The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, and the technologies available on the server. Since everyone’s site, traffic, and theme are different, there is no one-size-fits-all solution.
This is why there are no specific Guides for Woocomerce websites.
1. This depends on what you are trying to achieve. Woocomerce is calling the W3TC hook to purge the cache once something is changed. It also has the option to fragment specific parts of the woo website using ajax to avoid these parts to be cached

2. This depends on a lot of factors, however, Page Caching and Browser Caching are a good start.

3.a) The page is cached once visited. After the cache is purged for any page or all pages, it needs to be visited again in order to be cached if not specifically configured to be Preloaded.
b)c)d) In Performance>Page Cache, the re is a Cache Preload section. Once enabled and added the sitemap URL, upon the first visitation the W3TC starts to preload the entire website using the sitemap and by the Interval set in the Preload settings.
4. No there is no setting for this specific use case as you mentioned, so you can for example create a custom cron to call the w3tc_flush_all(); and after that call the cache prime using wp-cli
wp w3-total-cache pgcache_prime [–start=] [–limit=]

I hope this helps and let me know if you have any other questions.

Tanks!

Hello Stephen,

Thank you for reaching out and I am happy to assist you with this.
Purging the W3 Total Cache – cache all the time is not recommended as it may cause a lot of server resource consumption, naturally, it depends on the website.
There are a couple of things that you can do.
1. Exclude the page where the feed is (in your case /news/) from the page caching by adding /news/ in Peformance>Page Cache>Advanced>Never Cache following pages field.
2. Use Page Fragment Caching – You can check more details in our FAQ about this, but in short, you need to warp this part of the page with the mfunc, replacing the tags and excluding this part of the page from the cache.
3. Setup a custom cron on your server and call w3tc_flush_url($url); every x minutes/hours.

The last one is a programmatic solution that will only purge specific URL instead of pouring the cache for the entire website.

I hope this helps!

Hello Meg,

Thank you for reaching out and I am happy to assist you with this.
In W3 Total Cache settings, depending on the feature enabled, you can exclude specific pages from being cached.
In Performance>Page Cache>Advanced>” Never Cache following Pages”: add /cart/and also in
Performance>Minify>Advanced>”Never minify following Pages”:
Once added, make sure to save all settings and purge the cache.

Let me know if this helps!

Thanks!

Hello Andrew,

I am sorry about the issue you are experiencing and I am happy to assist you with this.
These are the configuration problems. You may be having some other plugins or manual rules that are in conflict with the W3 Total Cache settings and only a couple of tweaks can resolve the problems.
For your first question, and ion order to determine to the source of the problem, can you please disable the settings one by one in Performance>general settings, save the settings and purge the cache after each setting is disabled, and see which one might be causing the issue?

As for the .gz problem, The problem with downloading gzip files is probably that there already is a configuration in the setup that handles gzip files. If you enable gzip in Performance => Browser Cache => HTML & XML, the configuration gets messed up and the browser will download a gzip file in situations like yours. Disabling the gzip option in Performance => Browser Cache => HTML & XML will probably solve this issue.
You can also define W3TC_PAGECACHE_STORE_COMPRESSION_OFF constant that allows not to generate _gzip and similar files. It helps in the cases when the server configuration
doesn’t allow mime type overwrites so cached content ends up with browser
download action.
It’s located in /wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php line 1191

if ( defined( ‘W3TC_PAGECACHE_STORE_COMPRESSION_OFF’ ) ) {
return $compressions;

}
You just need to add define(‘W3TC_PAGECACHE_STORE_COMPRESSION_OFF’, true);

to the wp-config.php file.
Please let us know if this helps!

Hello Blaženka,

Thank you for reaching out and I am happy to assist you with this.
What this means is that the files and folder permissions on the server are not set as they should in order for the W3 Total Cache to be able to add the drop-in files, create a cache folder and write the .htaccess rules.
Can you please check the files and folder permission, and make sure that their permission is set to the following:
files – 644
folders – 755
Please make sure to check this article for more details.
I hope this helps!

Thanks!

Hello David,

Thank you for reaching out and I am happy to assist you with this.
You are correct when you say that the mentioned CDN provider is not listed in the CDN settings in the W3 Total Cache.
To include this as a CDN in W3 Total Cache takes some time because we are not the only ones that have a say in this.
For the time being, you can use the “Generic Mirror” CDN Type: in the General settings CDN section, and simply replace the URL with the CDN URL to serve static content from the CDN.
I’ll make sure to have a chat with the team and we may reach out to Cloudimage

I hope this helps!

Thanks!

Hello Alex,

Thank you for reaching out and I am happy to assist you with this.
The purge policy is defined in Performance>Page Cache purge policy. There you can find the options where you can specify the pages and feeds to purge when posts are created, edited, or comments posted.
The important thing to know is that the pages are also cached in the Browser Cache, using expires header and cache control header. In the W3 Total Cache, the default value is set to 1 hour.
Can you please try visiting the website in incognito mode or try to hard reload the page and see if the changes are updated when editing or posting a new post?
Thanks!

Hello,

Thank you for your feedback.
You are correct, I’ve checked Safari and yes, the problem seems to appear only on that browser. Other browsers do not have the problem you are referring to when visiting your website.
I’ve noticed that you have Lazyload option enabled, so can you please try to add the image URL to Performance>User Experience>Exclude words: field:
https://congregationofstpiusv.com/wp-content/uploads/2020/03/BpC-PiusCrestOnly-578x1164longer.png
Save all settings and purge the cache and let me know if the problem persists.
Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website on Chrome and Firefox, and I am not seeing the issue you are referring to, I do see that the W3 Total Cache is installed.
Can you please share which browser you are using and if you are still experiencing this problem?

Thanks!

Hello Joseph,

Thank you for reaching out and I am happy to assist you with this.
First of all, if you encounter any issues with the W3 Total Cache, you do not need to restore a backup, you just need to disable specific settings, save all settings and purge the cache and see which setting in Performance>General settings may be causing the problem.
For example, If you have Page Caching, Minify, Lazyload, and Object Cache enabled, one of these settings may be causing the problem you are referring to. When it comes to images it may be Lazyload or Minify (depending on how the image was embedded), and as for the header, Minify is an obvious reason.
Since you have not shared which settings you had enabled before removing W3 Total Cache, I am unable to provide any precise information on what may be causing the problem.
I would advise you to re-install W3 Total Cache, enable the settings one by one, save all settings, and purge the cache after each setting is enabled, (checking the website after every setting is enabled).

I hope this helps!

Thanks!
