I also have similar problem on homepage only. I get error below, displayed a few times above header.



Any idea what is it causing it?

Hi,
This means a problem with regular expression set for variables filtering in some extension. Open Manage Extensions page in JoomSEF and go through your extensions parameters. For each of them check that variables filtering tab contains only valid regular expressions. According to error reported it seems, that some regular expression contains wrong character range, so the lesser character is not before the greater (eg.: [5-3]).

Thanks for fast reply. The problem was in extention filter,RE "^[0-9a-zA-Z_-:]*$". I removed this and it works ok now. Btw, was RE badly formed?

Yes, the dash character must be the last in [] brackets, so the correct version would be "^[0-9a-zA-Z_:-]*$"
