Solved! Added a php.ini file to my public_html directory
I’m not entirely sure what caused the issue in the first place because I didn’t previously have the php.ini file and there wasn’t an issue, but for whatever reason, that glitch caused the site to need it now. Weird, but it works.
From the error log…
[Sun Jan 22 08:54:30.073325 2017] [core:alert] [pid 715181:tid 139653508192000] [client 98.169.32.38:62465] /home/keithebryanacp/public_html/.htaccess: Invalid command ‘php_value’, perhaps misspelled or defined by a module not included in the server configuration, referer: http://www.mysite.com/wp-admin/edit.php?post_type=page&page=apm_browse_pages_menu
I’ve tried uninstalling and reinstalling the plugin. I’ve tried updating my wordpress installation. Neither helped.
