I've been using Joomsef with the paid extension for some time and recently have gotten several complaints of incorrect user information posting during checkout causing one user to see another's information, and the checkout progress bar was broken as well causing incorrect redirects. Fortunately this problem was solved promptly and can be fixed by adding the following without quotes to custom non-sef variables in the Joomsef extension manager: "index.php?page=checkout.index&" please be sure to include this in future releases by default as this has caused major problems for us and we found several other users with the same problem.

I have this same issue, with joomsef 3, and I still have yet to figure it out. The Too Many Pages thread was not helpful in my case. Also if I restart apache the site will work for while longer then crash.

This is not a problem with the Joomla Core, in fact I saw this same issue occur on this site just a few days ago.

I just purchased Joomsef, and it works fine for a few hours after installation, but then it craps out, and when error reporting is on I get this message. Fatal error: Unknown function: () in /home/theoryshare/public_html/libraries/joomla/environment/uri.php on line 324 when error reporting is off then I get a white screen of death.
