Deleting Thread Error Message

Whenever I and the other administrators delete threads, we always get an error message. The error only shows up when threads get deleted, and not single posts. 
The error message looks like this:



Is there a reason for this?

In case you need the link to the forum, here it is:
http://www.warriorcatsworld.net/forum

Have you added any codes for hashtags?

@SLGray I don't see any JavaScripts installed on their forum, or I missed them..

@Bluestarrox97 is this every topic, or just certain ones ? Could you provide a link to the ones that don't delete. ( only if it's a select number )

has the names of the user or the posts got a @ or # in the names of the threads ?

I don't think so, I mean not that I know of. We only just discovered this error yesterday.

Sorry for the double post, but one of the other admins said that the error seemed to have fixed itself.

Is this topic now solved then ?

Hi all,
I faced the same problem yesterday while doing a little cleanup with my staff. Furthermore I have been delete the hashtag Javascript long time ago.

Is this still a problem ? we need to know so we can follow up on our reports

As far as I know, it hasn't been a problem on our forum, but it may be happening on other forums. I don't really know.

well if this problem is fixed for you then we can consider it solved.

You can archive it then
