in this case - fortunately - you didn't follow my instructions completely leaving Malik Umer's embed component still enabled. And since this component comes with a security hole (anyone outside may read any posting) I was able to find the broken record by doing some trial and error.
To get rid of that record:
Log in to your site with admin privileges as usual,
then enter the following line to your browser's address field:
You'll get a some way corrupted page this way, too
showing the avatar of Victor Hingsberg and a
Delete link below.
Simply click that
Delete link, and the posting will be removed.
Ignore resulting errors, just proceed back to https://torr.org/ossn/home
I'd strongly recommend to update your site to Osssn 5.x. which will handle cases like that correctly. As long as you're running 4.6: Don't delete users who had posted to other member's profile pages or asure these kind of postings have been deleted first.
