Re: chmod 755 errror on activating any caching plugin
You need to be able to change the file permissions that it’s telling you? config.ini
On a linux box at the cli you would do something like:
$ chmod 755 config.ini
if in the directory containing the file otherwise describing the full path to file /var/www/…
With cpanel ? iirc you can use ‘file manager’ navigate to the file and you should have options somewhere to change file permissions, try it and see.
an you upload images to your site, upload/change avatars? as you may need to relax permissions on wp-content as well but work back from the actual file before setting to many directories with relaxed permissions.
The WP codex has a useful page on WP permissions which you ought to read as it helps explain ideal file and folder permissions for a standard WP install.
