I am getting that same thing across several installs both 2.4 and 2.5. I have not started the 2.6 yet.

Server 500 error. I can not get it to upload as a user. I can not get it to import from a dir. All 500 errors. The thing stopped working just about as they installed the new php 2.2.4 on my services. IS anyone else find that same thing? Is there a relationship here?
