I purchased some add-ons last week and one of them is the Topic Prefix & Tag Manager.

After activating this add-on, I'm no longer able to write a new topic as the body (textarea) field has disappeared... pretty weird!

I deactivated the other add-ons again to make sure it's coming from the Topic Prefix & Tag Manager. Also, when I deactivate the Topic Prefix & Tag Manager, I see the body field again.

I have only a few minor css adjustments which have nothing to do with the new topic form and it happens in all forum layouts.

Any idea what might be causing the add-on to behave like this?
