I think it’s your server who’s causing such issues. If you can transfer the new single-playbit_album.php file to your child theme then it’d cause no issue from further on. I’ve fixed the issue as it was happening just because of your server. Also transfer the single-playbit_gallery.php file in to your child theme folder so that whenever a new update comes for the theme you don’t have to worry about the pagination & broken things.

Just copy these 2 files to your child theme & that’d be all.
