Thread:Project:Support desk/$wgUseSharedUploads causes trouble

Hi...

I'm running four interwikis sharing one pool wiki for the media files. After upgrading from 1.16 to 1.17 I'm getting an error, when I set $wgUseSharedUploads = true; in the LocalSettings.php of each interwiki.

Here is the error:

Warning: mysql_real_escape_string expects parameter 2 to be resource, null given in /html/wiki/en/w/includes/db/DatabaseMysql.php on line 318

Warning: mysql_real_escape_string expects parameter 2 to be resource, null given in /html/wiki/en/w/includes/db/DatabaseMysql.php on line 318

Warning: mysql_query: supplied argument is not a valid MySQL-Link resource in /html/wiki/en/w/includes/db/DatabaseMysql.php on line 23

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: BEGIN from within function "DatabaseBase::begin". Database returned error "0: ".

It's very brutal, because no images show up, except for the pool wiki. I'm about to try MW 1.18 alpha, because I have no idea how to fix this and I really need the images.

Any help is more than appreciated!

Thanks + cheers,
