[Plugin: Mingle Forum] Editing an article shows its contents in HTML

Hey. I’m echoing what another user has said — when you click on edit — the post shows up with the HTML tags on each line. Then when you go to save the post, it saves the HTML tags as actual characters. Anyone know what’s causing this? Everything else on the forum is working perfectly.
