WordPress MU

So, my Wordpress installation is up and running. Everything works, except, when I go to enable new templates. When I click submit the page automatically redirects to 1and1 (my host) Error 500-Internal Server Error. So the problem come, because I don't have any templates installed. So I can't deploy the website until I get templates up, but it simply won't let me. I would appreciate it if someone would help.

Thanks,

you probably have problem with permissions.
Please make sure that Folders are CHMODED to 755
Files CHMODED to 644

Some of you might have run into the same problem I did. I was getting an awful error message on my sites.
"500 Internal Server Error"

I searched all over the forums only to find minimum help. I even e-mailed tech support to my host provider and they told me to use more of their products because it was a problem with my wordpress installation.I went in and deactivated all the plug-ins that I had activated. Finally coming to one that was the problem.

"WP-Cache 2.1.2 Plug-in - Very fast cache module. It’s composed of several modules, this plug-in can configure and manage the whole system. Once enabled, go to “Options” and select “WP-Cache”. By Ricardo Galli Granada."

I went into the options and deleted the cache. Then deactivated it and BAM! back to normal.

Good luck everyone!
