I have two issues after installed W3 Total Cache,
1. When I installed both AssetCleanup and W3 Total Cache,
I can not deactivate one of them but I should deactivate both.
And I have to deactivate both before creating or editing a new post.Why?
2. The W3 Total Cache error messages after installed Version 2.1.6, Aug 6, 2021 as the followings:
And thanks to the following errors, I am unable to remove this plugin as well.W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/sungwn5/public_html/wp-content/advanced-cache.php.
W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/sungwn5/public_html/wp-content/db.php.

Hello SUngwook,
Thank you for reaching out and I am sorry about the issues you are experiencing.
1. I’ve tried to replicate this and I have no problems deactivating and removing either W3 Total Cache or Asset Cleanup plugin. Make sure that Minify is disabled for logged in users in Performance>Minify, save all settings and purge the cache and see if the problem continues to occur.
2. Try to manually remove W3 Total Cache:
1. Purge Cache
2. Deactivate and Delete Plugin
3. Check .htaccess File (make a backup)
W3TC will create many directives in the .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”.
Ensure that no residual entries are leftover in your .htaccess file after deleting the plugin.
4. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– db.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (if exists)
5. Delete Cached Files from CDN (if using CDN)
Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser.
6. Go to your wp dashboard and re-install W3 Total CacheI hope this helps!
Thanks!
