I have downloaded W3TC on my WordPress site
However, even if I repeatedly click on “activate”, the plugin will remain inactive.
What am I doing wrong?October 1, 2020 at 2:09 pm #27763Brad MarkleKeymaster
Hi giacomo. I’m sorry to hear you’re having trouble activating W3 Total Cache. Can you answer the following questions to help us troubleshoot further please:
October 1, 2020 at 3:13 pm #27773giacomoGuest
- Have you ever installed W3 Total Cache before on this site, or is this your first time?
- Are you getting any error messages? If not, are you able to see any warnings or errors in your server logs? (You’d probably have to contact your web host if you’re not sure)
- Do you have any existing cache setup? For example, do you have another caching plugin installed, or do you have redis / mecached installed on your server?
Wow that was a fast answer!
I had litespeed installed and now I deleted it. I get no errors whatsoever.
What do you think?October 1, 2020 at 3:36 pm #27791Jesse OwensKeymaster
It looks like your web host installs LightSpeed Cache by default on all their WordPress hosting plans: https://xlogic.org/blog/nuove-funzionalita-per-il-plugin-lscache-di-litespeed.html/
According to that article, “In all WordPress sites the LSCache plugin is automatically installed from our system…” (Translated by Google Translate)
Given that, it’s possible that they might not allow you to install other cache plugins, and it might be worth reaching out to them to see if that’s true. Some web hosts enforce this, and in those cases the issue usually has the same behavior as you’re seeing- that you click “Activate” and it simply won’t activate.
That being said, we might be able to get more information about the issue if you can enable WordPress debugging mode by setting the following constants in your wp-config.php file:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
Once you’ve set those, try to activate the plugin again, and check your wp-content/debug.log file to see if there’s any more information there.
