This can be caused by multiple things.

• First, please check if you have active a plugin named ‘Really Simple SSL’. If yes, please go to it’s settings and deactivate ‘Redirect Javascript’ feature. This feature can cause hangs in rule running.
• If the above did not solve the issue, please increase in plugin’s ‘Main Settings’ the ‘Rule Timeout’ parameter. The endless loop can be caused by a timeout in the plugin.
• The third thing to try is to check the plugin’s ‘Activity and Logging’ section for errors. If you find any errors there, please report them to my email address: kisded@yahoo.com
