Error message mentions wp_supercache on WP.v.5.8

  • When trying to load the edit page for either a site post or a site page, all I get is a blank white page. All other pages load correctly. I see the following error message on my server in the syslog file:

    [Thu Jul 22 20:36:57.437280 2021] [proxy_fcgi:error] [pid 8493:tid 140608078694144] [client x74.110.xxx.xxx:53132] AH01071: Got error 'PHP message: PHP Warning: include_once(/home/ftpusers/redacted/forum.domain.com/www/wp-content/plugins/wp-super-cache/wp-cache-phase1.php): failed to open stream: No such file or directory in /home/ftpusers/redacted/forum.domain.com/www/wp-content/advanced-cache.php on line 22PHP message: PHP Warning: include_once(): Failed opening '/home/ftpusers/redacted/forum.domain.com/www/wp-content/plugins/wp-super-cache/wp-cache-phase1.php' for inclusion (include_path='.:/usr/share/php') in /home/ftpusers/redacted/forum.domain.com/www/wp-content/advanced-cache.php on line 22', referer: https://forum.domain.com/wp-admin/edit.php

    All the files mentioned above are there in the mentioned locations.

    Things I have tried:
    Increased php memory on server to 768MB in the php.ini file.
    Renamed plugins folder to disable all plugins, cleared site cache, autoptimize cache, and browser cache
    Disabled supercache and re-enabled
    Removed and re-installed wp_supercache
    Used the default theme and not a child theme.
    Enabled debug mode in wp_config.php and got this message on the blank page:

    Deprecated: block_categories is deprecated since version 5.8.0! Use block_categories_all instead. in /home/user/public_html/domain.com/www/wp-includes/functions.php on line 5458`

    My web search results showed other plugins that had this problem during the development phase of v.5.8, but I see no mention of it with regards to the wp_supercache plugin. So, I am starting my search for a solution with the plugin since it is mentioned in the error message on the server. This problem started immediately after the upgrade to v.5.8. I am currently using php version 7.4.

    Any ideas or suggestions would be greatly appreciated.

    Upon further investigation and trying many things, I have just realized that there is some kind of browser incompatibility with the waterfox browser. It works fine in both the Firefox and Chromium/Chrome browsers.

    I will mark this as <Solved>.
