Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
I’ve tried both, and it’s the same message when I try to change theme…
How did you reset the plugins folder? Using Phpmyadmin? If not, try that.
I reset the plugins folder by replacing it by the plugins folder coming with the install package. I’ve made a simple move unix command. And I get the same message.
And I’ve tried too to replacing the themes folder by the one which comes in the install package, and I get (again and again) the message “Cheatin’ uh?”.
Any other ideas ?
It’s a multisite WordPress, here’s one (but there’s the same problem with all other sites) :

Have you tried setting up a test single-site install on this server?
No, but it would take time. A test with the same plugins and themes ? Is it really necessary ?
It would help to confirm whether this is a Multisite specific issue or if it’s being caused by a server configuration problem.
OK I try ASAP and keep you in touch
I am having the same issue with twentyten on a single site install…
Interesting… although very frustrating for you, I’m sure. This means that it’s more likely to be a server issue. I’ll ask around and see if any of the other forum volunteers have come across this situation before. In the meantime, did you create this new site using a fresh download of WordPress?
Another thought: Have you tried emptying your browser cache and deleting your cookies?
I know this isn’t a good solution, but I rolled back my installation to a previous version of WP and the error message disappeared.
