Help! I upgraded Server and now my admin gives me a 500 Error page

I am in need of some quick advice. I had upgraded my server, now I cannot access the Admin Settings in the backside of store, I can access other pages, just not this one. I placed a dummy order and was wondering why I did not receive a email confirmation...I tried to access the Admin Settings under Tools and I receive a 500 Error page. :shocking:

Can anyone give me some advice other than contacting my hosting company...they are next to contact after I post this.

Thanks

"I had upgraded my server, ..." Can you further explain this.

Probably there is something wrong in the configuration.php files. Have you updated them after your upgrade, whatever it means?

Thanks for your reply... "Upgrade" - I changed my account that required a new ip address and moved all files to that ip address..thus...upgraded. When I posted last night, I was very tired. You are correct...the folder's permission wasn't set properly. All is ok now.

Thank you
