I'm used to SilverStripe now and i just don't understand what i happenning.
I'm able to insert images into the "Files & Images" tab in the admin but when i click on the "Insert image" button in TinyMCE, i should open a panel to the right of the editor to allow me to select my image but it doesn't. I tried googling and searching the forum but i can't find a solution. Can anyone help me?
I had the same problem and some other login issues not related to this tinymce image bug. But after reading this post http://www.silverstripe.org/form-questions/show/254340 which descibes a session problem and how to modify some lines in the Member class to fix it (I know it is not the best solution when it comes to security.) the images suddenly show up again.
