Hey,
Firstly, I haven't edited any templates.
I have a problem with the font/text size/colour drop down boxes:
Any help is much appreciated.
Isn't that a different theme you have installed?
You could try re-uploading ./jscripts/editor_themes again to see of the upload has missed a file, or corrupted one.
Unfortunately that didn't work
Maybe ./jscripts/editor.js
I reuploaded the whole /jscripts folder,...nothing
Ok, URL and test account??
What browser are you using?
