Lately I'veen getting 404 on the backend... for example when you try to update a plugin, instead of getting the new screen I get a 404.
If I refresh the page I get the correct one.
Am I the only one getting this type of problems? For me it is happening every 5 to 10 screend in the backend (sometimes when posting, when activating or de-activating a plugin, etc).
I haven't been able to find a pattern yet that's why I'm trying to see if anyone else is having similar issues.
I'm running a WordPress 3.0 installation on Dreamhost with a custom theme (that never gave me any problems for the last 2 years) with only one hook on the functions.php file (body_class()).
I've tried deactivating plugins and some other tests.
Any other ideas?
