I am not sure if it is the same problem I am having because I don't get an error message, just a notice that I have an infinite loop on my homepage. If I turn off this feature in the advanced settings of JoomSEF, my homepage starts working... Redirect nonSEF URLs to SEF: No

Hi,

noirebene: The "MySQL server has gone away" error usually means some problem with your MySQL server, as it means that the connection to MySQL has timed out. The SQL query looks all right, so I'd recommend you to contact your server hosting company to see if they can find the cause of this problem from server's errors log.

jewsforjesus: Your problem is not related to the original thread topic, so please start a new thread. Also please post there the version of Joomla and JoomSEF you use and some example of the problematic URL.
