I've upgraded from 2.7 to 2.8.3.SP1 incl. the Hotfix. (the 2 latest downloads)
Everything worked just fine except for the images in the wysiwyg editor (fckeditor).
That's how i got to the .htaccess"trick". After that everything went into oblivion....
I've deleted the file via phpmyadmin...no changes sadly
Reloading and upgrading of the modules does not work, because the admin gives me also a blank page.
The source of every page possible, gives me the generated code you see above (emty body-statement).
While I was waitin' for your answer LOL, I've tried to give it a new install, but that doesn't work either.
It shows the install-page, but after clicking "install" it gives me a blank page in return....
I'm totally lost
