I had installed Joom!Fish on my Joomla! site to support Mandarin Chinese. When Extended Menu module is installed, I got an error like “Deprecated use of Mambelfish …”
After some search, I fixed the problem by:
“comment line that is line $GLOBALS[ ‘mosConfig_mbf_content’ ] = ‘1′; .
This is inside mambots/system/jfdatabase.systembot.php.”
