Greetings!
After the upgrade Joomla to 2.5.18 there was a small bug. Before the update, everything was fine. It lies in the fact that if you just make a comment then all is well, but if you make a response (reply), then an error "Internal Server fly out in error" and the dialog box. If you close it and refresh the page, the comment despite the error appears.
Prompt, in what could be the problem? Thanks!
