Empty string supplied as input when parsing content
I have fixed the problem. The main problem was that I was calling the function mb_find_my_image from index.php. After I’ve removed the calling from index.php, everything works as it should.

Unautop / Sanitize content added to a post through a plugin
A couple of caveats before beginning. It tried to run that plugin but apparently I have to register with a third party site before I can use it, so that throws a wrench in testing.
