I love this plugin but it is now giving me an issue and I cannot save any changes from the settings page, I get this error (only on this plugin, all others are working fine):
You don't have permission to access /wp-admin/options-general.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache Server Port 80
Seems quite a common error but cannot find a real answer anywhere - I have searched and found suggestions for mod_sec in .htaccess file but they have not worked for me. Also deleted and reinstalled the plugin, but still the same issue.
Any ideas on the problem or how can I make changes to the settings without using the settings page.
Many thanks in advance.
