Greetings! W3 Total Cache kept crashing my site so I disabled it, but trying to delete it crashes the site too, so it is sitting inactive in my plugins. For months I have been getting emails from Siteground that my hosting plan has reached its max Inode quota. I keep deleting the cache file in wp-content as instructed by Siteground but would love to get to the bottom of this. They said I should advise you that the cache file keeps growing. As you can tell, I am not a developer. Can you please help me fix this error?
Hello Eva,
Thank you for reaching out, and I am happy to help!
W3 Total Cache is the most complete optimization plugin with a lot of optimization settings and caching.
Depending on the configuration, you may have set everything to cache to disk. In cases where the Inodes are limited and on shared hosting, it’s not recommended to use the Disk caching method with Object Caching and DB Caching. And in this case, depending on how big the website is, it may create a lot of cache files and therefore hit the limit.Can you please share the content of the wp-content/cache/ folder?
Also, if you manually delete the /cache/ folder, is it created again?Thanks!
Hi Marko- Thank you for your reply! Most of this is over my head but I will tell Siteground and hopefully they can instruct me how to fix. The plugin is not currently enabled.
Yesterday I deleted the cache folder and this is what is back today:

thank you!!!
Hello Eva,
Thank you for your feedback.
If the W3TC is disabled, it will not create any files. You can safely delete the cache folder manually, and please check if you are using any other plugin for caching like SG optimizerWith the W3TC files should be cached in /cache/page_enhanced/yourwebsite.com/ folder
Are those files there?Thanks!
They’re not. The file path is Cache>Object> see screenshot or am I looking in the wrong place?
Just realized I cant attach it. Under Object there is not “page enhanced” – there are no listed folders between Options and Post Queries. I think I need to get Siteground involved.
Thank you Marko! W3TC has been disabled for months so maybe the SG Optimizer is causing the problem. I will check the folder you suggested now. I’m a travel advisor and all the last minute trips for Sept are taking focus from this.
Hello Eva,
Thank you for your feedback.
So the files are in wp-content/cache/object/ folder.
If the W3 Total Cache is disabled and you may have Object Caching enabled in the W3TC settings, and if the caching method was set to Disk, those files may be cached in that folder.
As I’ve mentioned before, it’s not recommended to use Object Caching if the only option for caching is Disk.
Please make sure to delete the entire /cache/ folder. Wait for one day and see if the folder is created again.
Please check if you have any other plugins that may be doing the Object Caching or any other form of caching
Check the wp-content folder for the object-cache.php file and check if that file is a W3TC drop-in.I hope this helps!
Thanks!
