 * Hello,
    Just to confirm, Is the issue occurring when W3 Total Cache is enabled
   or disabled?

 * Hello,
    Please follow the steps below to completely remove W3 Total Cache: Assuming
   that W3 Total Cache is installed: 1. Purge Cache (if you already uninstalled 
   W3 Total Cache skip this step) 2. Deactivate and Delete Plugin (if you already
   uninstalled W3 Total Cache skip this step) 3. Check .htaccess File (make backup)
   W3TC will create many directives in .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 left over
   in your .htaccess file after deleting the plugin. 4. Delete wp-content files 
   and folders – cache folder – w3tc-config folder – dbcache.php (if exists) – object-
   cache.php File (if exists) – advanced-cache.php (if exists) – upgrade folder 
   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.
 * This will completely remove W3 Total Cache from your website.
    If the issue persists
   after these steps, it is not related to W3 Total Cache.
