 * Hi folks,
 * I use the subscribe-to-comments-reloaded plugin. When a user clicks on the confirmation
   link in the mail, he gets error 503.
    If I deactivate all security functions,
   the mail subscription page can be accessed. What do I need to set so that users
   can subscribe again?
 * Regards
    Michael

 * The 503 error essentially means “service unavailable”, which might be caused 
   by the extra load from the security plugin.
 * What version of PHP are you using?
 * Do you have the opcache PHP module active?
 * What are the values of your PHP settings memory_limit and max_execution_time?

 * Hey Buddy,
 * thanks for the reply, But I edited my last posting: It’s only a 403 (forbidden).
   I guess, a simple problem for you.

 * The 403 forbidden error is normally caused by one of the features which uses .
   htaccess directives. For example, the firewall rules, the blacklisting feature
   or the white list feature in the brute force menu.
 * If you go to the AIOWPS “Settings” menu, you can “Disable All Firewall Rules”
   This will clear all the firewall rules from your .htaccess file. Can you disable
   them and then re-enable them one by one until you find the offending feature.
 * Can you let us know which feature is generating the error message?
