I'm running into a strange problem. I have a site that is managed by a client. A couple of days ago, they started noticing that things weren't working correctly in the admin. I checked it and found that there were errors showing up in the dev console. Here are the errors I get on the admin landing page:
NetworkError: 403 Forbidden - ...admin.php?S=11606155886845716ce19d7cdde155fc5d604080&D=cp&C=javascript&M=load&file=css&theme=default&v=1312216958

All JavaScript interaction is killed (dropdown menus, tabs, etc.), and it happens in all browsers. I've checked all the file permissions that I'm sure about and they haven't changed. As far as I know, nothing has been touched for a long time on the server. The client makes frequent updates to the site, but I don't see how they'd be able to cause such errors.
Granted, it's an older version (v 2.2.2), but it's been working fine up until a few days ago. Anyone have any ideas?
UPDATE: Nevermind, folks. After finding the same thing happening on another site, hosted on the same server, I've determined it was a change in the server config by the host. Currently working it out with them.
