Weird out-of-memory errors!

Hi!

WordPress is behaving oddly all of a sudden! When I’m trying to access the admin page I get a PHP memory exhausted fatal error. I asked the host and they claimed they have not changed the memory limitations. Same thing happens when I view the main page.

The admin page error happens in the admin-functions file on line 1241 which is in the middle of a parent-dropdown function. The main page error happens in some include file called “snoopy-class” or something similar.

The REALLY weird thing is that I’ve done NO changed to wordpress whatsoever in a very long time so can’t even blame myself for fiddling around and messing something up.

Anyone who knows what this is all about and how I can fix it. The only solution I see at this moment is try try and reinstall everything ??
