turns out there was a *possible* security issue with XOOPS 2.0.x prior to 2.0.7, this issue applies to almost all cmses, it's an issue in a shared hosting environment where another user on the same server could include *your* mainfile.php
anyways, this sounds like a question for a XOOPS guru to help with, i'm not sure how that block could have changed appearance, because even if your browser was loading an old cached webpage, the Make a Donation button should still have appeared.
