Thread:Project:Support desk/InstantCommons ... images disappeared

The WikiCommons images on a site I am running instantly disappeared.

I am using the InstantCommons feature - configuration: $wgUseInstantCommons = true; I have not configured "$wgForeignFileRepos", as described here: http://www.mediawiki.org/wiki/Manual:$wgUseInstantCommons

I see that someone else has had this issue -- based on a message here; however, no resolution is described.

I do note that there is a limit on downloads (1GB?), as described here. I cannot imagine that I am near that and I don't understand how that could cause this problem.

I didn't change settings on the wiki recently. I did add the extension WikiSEO a few days ago. I cannot image this is the problem.

The wiki is here: http://librepathology.org

The version information: MediaWiki 1.23.2, PHP 5.4.4-14+deb7u14, MySQL 5.5.38-0+wheezy1 -- see here.

Any help would be appreciated. Thanks!
