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?
