Css, images and subpages break after connecting custom domain

i built a blog using github pages, under the default github url everything worked perfectly.
after connecting a custom domain, only the index page loads, css and images seem to be disabled.

the site: www.madantunim.com

Hi @DoronGurel, welcome to the GitHub Support Community! I’m able to visit other pages on your site without any problems. Did you manage to fix this or is the issue still happening?

If you’re still having trouble can you post some direct links to the pages you’re having trouble with and maybe a screenshot of the issue you’re seeing?

Hi @DoronGurel, I am having a similar issue. Do you mind explaining how you managed to fix it?
