I can't edit text using the editor and I have two posting boxes? Even on this site, the main forumotion site, I have this issue.  I linked a screenshot below. I was trying to bold the highlighted text but nothing happens. You can see the boxes above and below the editor.

Do you have any Javascript installed on the forum?

No Java installed at all.

Could you provide a test account with posting rights.

I don't think there would be a point. There was one member one my site that was having the same issue as me but it fixed for her after she tampered with something. We just can't figure out why it wont work for me now. I'm literally the only one on my site that has this issue now. I doubt you would have it if you can post on here fine. xD

Each site can have different settings, and what not it may be a number of things, the test account can be used to check the console for errors and what not.
