[Tue Sep 10 15:42:21.956484 2019] [php7:error] [pid 16275] [client 34.207.79.107:54800] PHP Fatal error: require_once(): Failed opening required ‘/nas/content/live/project/wp-content/plugins/404page/inc/class-404page.php’ (include_path=’.:/usr/share/pear/php:/usr/share/php’) in /nas/content/live/project/wp-content/plugins/404page/loader.php on line 26
We confirmed this class-404page.php file exists.
Our site is running on several different environments.
It’s working fine on my local, but WordPress Engine Staging is failing.
Hope this helps identify a path for fixing.
