Forum:Error Uploading new logo

Hello, I recently migrated my wiki over to Wikia's servers, and I have had some trouble getting things up to date again. Chief among them, whenever I attempt to upload a new logo (Wiki.png), I get an error reading:

Internal error

Could not rename file "public/b/bc/Wiki.png" to "public/archive/b/bc/20080815121127!Wiki.png

Does anyone have a way to resolve this, or know what I am doing wrong?

Thank you very much.
