Update of the theme "Anarcho Notepad"

This project is temporary frozen. www.remarpro.com is changed the rules of the publication of a themes to their repository. And now, I can’t publish update of the theme, because of the following error:
REQUIRED: Found a Customizer setting that did not have a sanitization callback function. Every call to the add_setting() method needs to have a sanitization callback function passed.

I’m doing everything possible to do update this theme, but I have not enough time to solve this problem.

If you have the desire then you can help me in resolving this situation. For testing the theme use the wordpress plugin “Theme Check“.

Thank you
