hi bug: https://sourceforge.net/tracker/index.php?func=detail&aid=983680&gr… The Problem comes from this lines in Title.php << # Initial colon indicating main namespace if ( ":" == $t{0} ) { $r = substr( $t, 1 ); $this->mNamespace = NS_MAIN; } else { (...) } I removed all this code portion (not (...)), and it seems to work. I don't understand why an initial colon should indicate the mainspace... and why an article can't start with ":" ? But I'm a newcomer :) So I hope that's an acceptable solution, otherwise a message on the loginform with login rules could be appropriate ?
