PHPMyAdmin won't Browse :(

I've been using PHPMyAdmin for a while, and recently its decided to no longer let me browse my databases. Everything else works fine. Instead, it just reloads whatever page I happened to be on before I clicked on Browse. This happens whether I click on the Browse tab or enter a MySQL query.

I'm using PHP5 and PHPMyAdmin 2.5.7. Google has turned up nothing, so if anyone can help me I'd be very appreciative! ;)
