Add new post gives blank page

Hi!

I'm trying to solve a problem that I have with Easyblog.

When trying to add a new blog entry, I've got a blank page both in frontend and backend.
First of all I wanted to update the easyblog version, and picked the API-key from the dashboard.
But the updater says it's a faulty code. So I can't update.

A little googleing gives that there might be a conflict since I'm not using tinymce as editor.
It's still installed and activated, but not default on my site. Didn't help to set it as default either..

Please advice..
