Are you using the BulletProof Security plugin:

– reading the troubleshooting 3.5 master list to see if any of your problems is listed there: http://wordpress.org/support/topic/troubleshooting-wordpress-35-master-list
– flushing any caching plugins you might be running, as well as server and/or browser caches.
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems.
– re-uploading all files & folders – except the wp-content folder from a fresh download of WordPress. by using FTP or whatever file management application your host provides (Manual Update).
– re-running the upgrade via wp-admin/upgrade.php
Could you elaborate a little bit more.
My content editor is not working. I cannot edit post or create new posts. It is completely blank.
Are you using the BulletProof Security plugin?
So you did all the troubleshooting steps (deactivating all plugins, switching to the default theme, re-uploading all files & folders)?
I deactivated all plugin and still not working.
I don’t know how to re upload all files and folders. My site is working so I don’t want to mess that up. I am afraid that if I start messing with stuff I will mess my site up.
Well, if you don’t “mess” with stuff, then you can’t actually fix the problems you’re having.
Your issue in particular is most likely a problem with your .htaccess files in some manner. A took a look at your site, and the main problems are definitely coming from bad rules you have in there somewhere.
If you have an .htaccess file in the wp-admin folder, then delete it. It should not be there.

Elaborate on that, please.

Otto, thank you very much! The problem is solved. There was a .htaccess file in the wp-admin folder. I removed it. I didn’t put it there myself but I think that there was a safety plugin which has done it. I don’t know which plugin.
Do you tell me that there are bad rules in this file? Can you tell me how I can fix this?
new media manager does not work! When I finished the upgrade to 3.5 german (without error), I recognized that I can’t insert medias into an artcitle. I also can’t upload new images. Opening the Media I see all the images I already have uploaded bevore. What is going on there??
This WILL solve it. i found it here. u have to add some lines to your wp-config.php. sad that its broken. real sad 🙁
