First, the “Fatal error: Uncaught Error: Call to undefined function ctype_xdigit() ” error means your PHP requires a module that’s isn’t installed. It happens for example when you switched to a new PHP version (like PHP 8). We recommand you to check if all your old modules from PHP 7.x are now the same on your PHP 8 migration. Usually, you can do it on your Webhosting.

If this doesn’t help, we also recommend you make sure that your theme (and plugins related to the theme) are up to date, either for the free or for the pro version of this theme.
