I have the following plugins installed on my WP multisite installation.
New Blog Templates
Log In Message
Google Analytics +
WPMU DEV Dashboard
Multisite Content Copier
Some plugins that I try to use gets blocked by admin-ajax.php requests are blocked with an “302” error (‘302 Moved Temporarily’). This can be caused by the template or a plugin which is trying to block non-admin role users for requesting the wp-admin/ directory.
I have tried to disable plugins and fins out which one is causing the problem but without success. Could someone tell me if any of the plugins listed above could cause this problem?
