[jp.bond]

hi,

 

(first, excuse my english, i'm a froggy french.. ;-) )

 

I have install the 2.2ms2fr version, admin part is ok but when i try to access to the online catalog part, ihave this funky error :

 

Fatal error: Class messagestack: Cannot inherit from undefined class tableblock in /home/user/e/n/e/energy4000/www/boutique/catalog/includes/classes/message_stack.php on line 20

 

i 've tried to update this file by ftp...but nothing changes...

 

any idea ?

thanks a lot !
