Whenever I click the 'edit sumary' icon, I am presented with a screen that only shows my header and nothing else.
I have tried changing themes and get the same result.
I recently upgraded to 2.5 and the server met all the requirements.
I have been able to edit summarys in the past but don't know when it may have stopped working as it's been awhile since anything was done.
TinyMCE works in other areas for editing.
