Hi!
In W3 Total cache > Performance > General Settings > Page Cache,
The “Purge Cache” and “Empty Cache” button is not working.
No matter what configuration I try to use, the “Empty Cache” button redirects me to
https://web/?w3tc_note=flush_pgcache
Which displays in the Browser: ERROR Page not found
When using “Page Cache Method: Disk: Enhanced”, the files are created in the /wp-content/cache/page_enhanced/ folder successfully. But the Purge Cache and Empty Cache buttons do not delete any files inside that folder.
When using “Page Cache Method: Opcode: Alternative PHP Cache (APC / APCu)”, the files are created in the /wp-content/cache/page_enhanced/ folder successfully.
But the Purge Cache and Empty Cache buttons do not clear up the APC memory. I confirmed by checking the server APC statistics (via this method https://www.php.net/manual/en/apc.configuration.php ). I am able to clear my own APCu memory in the server, but not* through the WordPress W3 Total cache Plugin Page.
Is this a problem with the plugin or with my installation/configuration process?
Lastly, there is one odd thing I want to ask about. After enabling preview mode in WP Admin > Performance > General Settings > General > Preview Mode > Enable , and then going into the Preview of my Site, the Query Monitor Plugin shows the following message:
“The APCu extension for PHP is installed but is not in use by WordPress”
“External object cache not in use
Opcode cache in use: APC
Opcode cache in use: Zend Opcache”
I can confirm that APCu indeed contains entries such as “w3tc_1738895883__0_pgcache_edc15ea8a41c1071c1bd31db5622704f_ssl_gzip ”
“w3tc_1738895883__0_pgcache_edc15ea8a41c1071c1bd31db5622704f_ssl ”
So I am wondering, how do I confirm that the Site is actually showing the Users the static HTML pages from APCu?
thanks,
