I’ve disabled all of my plugins. There are these lines in my functions.php:

remove_filter('the_content', 'wpautop');
remove_filter('the_excerpt', 'wpautop');

But WordPress still adds random

tags to the source without the opening tag. I’ve tested this site a few updates before, I have not noticed anything like this. The theme written by me. Thanks for you help.

Update:

This problem only exists on post edited with HTML. No random tags in post written in visual editor.
