Thread:Extension talk:GlobalUsage/Prefix of table globalimagelinks/reply

The database code resolves the canonical name into the actual name (adding the prefix) automatically. If this doesn't happen that can mean one of two things:
 * There is a bug in MediaWiki core where it doesn't do it properly
 * The GlobalUsage extension is using raw queries instead of abstracted through MediaWiki's handler.

Please file a bug on Bugzilla (Product: MediaWiki extensions; Component: GlobalUsage). Be sure to include the version of your wiki and the version of GlobalUsage (you can get this information by going to on your wiki). If possible, also include a link to your wiki in the bug report. Thanks!
