Hello,
You missed to provide FTP access to your site. I suppose that problem caused by your child theme and changes that you made there, especially in theme-functions https://prnt.sc/11iyywz
If you want to change any function you need to copy only function code (not whole the file with all the functions!) from parent theme to child theme fucntions.php and edit this function according to your needs.
Provide FTP to check my guess.
Regards
