Hi,

With this link :
http://ez.no/doc/ez_publish/upgrading/upgrading_to_3_10/from_3_9_x_to_3_10_y

we migrate our site. But in the B.O. ant the F.O. we doesn't seen the content.
In debug of B.O. we have:

Warning: PHP  	Apr 29 2009 16:53:53

call_user_func_array() [<a href='function.call-user-func-array'>function.call-user-func-
array</a>]: First argumented is expected to be a valid callback, 
'eZNodeviewfunctions::contentViewGenerate' was given in /app/oppbtp/htdocs/kernel
/classes/clusterfilehandlers/ezfsfilehandler.php on line 432

Error: 	Apr 29 2009 16:53:53

Write callback need to set the 'content' or 'binarydata' entry

What is the cause?

Thanks,
