There were too many issues with the editor so figured I would put them all in 1 topic.
1. Clicking on the FONT button of the editor shows a blank list. Mousing over it will highlight the fonts. Same for SIZE button. COLOUR button list shows ok, except for Beige. Hard to see it against the white background.
The LIST button on the end also is empty. It also doesn't have any tool tip.
2. Selected 'Help' from the Button Mode and clicked Align Left button. I got:

This goes for majority of the buttons.
3. Selected 'Prompt' from the Button Mode and clicked Align Left button. The OK and Cancel buttons don't flow like how you have it for the rest of the forum, where the Cancel button is on the left, and the Ok/Post button on the right.
4. Still on the Prompt mode, some of the buttons do not have any helpful text when clicked on. For example, Align Left button shows "Text to Align LEFT" then a text box in the pop up. Italicize just shows a text box. Same for:

• Italicize
• Superscript
• Subscript
• Horizontal Line
• Youtube video
