I get this randomly and I'm not sure what the cause is but sometimes when I make posts I get this small box below where my post is. It's like a one line quote box right under my post.

There were some others but I removed them by pressing delete at the end of the post a couple times although it didn't work all the time. Also when I click on edit it doesn't show the box.
Looks like the "Quick Translator" plugin may be the culprit. The color scheme seems to match.
Ah I did have that installed. I was posting when I saw on swiftfox so that probably was it. That's a bit odd for it to affect a forum post however. I don't have it installed now so hopefully it doesn't show up again. Thanks.
