Hi,
On the error console there is a 403 error for all plugin assets, meaning that the files are not accessible, the server refuses to give access to them. This includes the scripts as well as the stylesheets: https://i.imgur.com/cATDnyi.png
The most likely cause is a permission change on the server side or a firewall block. I recommend these steps to resolve the issue:
– Make sure the wp-content/cache folder exists and it’s writable. The folder permissions should be 0755 and owned by the www-data user if you are using apache with mod PHP. If you are using PHP-FPM, please consult the server admin about proper folder ownerships.
– Also make sure the wp-content/cache/asp folder exists with the same permissions and ownerships.
– Check the apache mod_rewrite rules for any blocks for the upper mentioned folders
By default all of these should be just fine, unless the permissions or ownerships were changed on the server side by either a plugin/script or manually.
