Thread:Project:Support desk/ Unsupported operand types

hello everyone !

i wanted to try something with my mediawiki, i wanted to put my 1.24 install (future production, functioning properly) on the same DB with the 1.19 install (production) then, comes the problems :D :'(

My 1.19 install doesn t work anymore, i m getting those errors :

Warning: Invalid argument supplied for foreach in /usr/share/mediawiki/includes/LocalisationCache.php on line 362

Warning: Invalid argument supplied for foreach in /usr/share/mediawiki/includes/LocalisationCache.php on line 422

Fatal error: Unsupported operand types in /usr/share/mediawiki/languages/Language.php on line 345

i really don t know where to start to solve it, anyone got those errors before ?

thank you in advance
