Booking Calendar - Cannot Book - Server Error

Hi Tim.... having issue with a booking calendar that I am creating. It is for a special event. I created one last year around the same time and it worked fine... I believe it is something the my host has changed but was hoping that you could tell me where to look or what to address to my hosting company. Here is the error I am seeing in the server logs:

20210331T153412: www.randallkenneth.com/sy-inc/booking-calendar-options.php
PHP Fatal error: Uncaught Error: Call to undefined function eregi() in /hermes/bosnacweb02/bosnacweb02cd/b2902/dom.randallkennethcom/randallkenneth.com-redirect/sy-inc/functions.core.php:61

Thanks for any help...

The problem is that the ctype functions are not enabled in the PHP configuration. You will need to contact your hosting company support and ask them to add the ctype functions to the PHP configuration.

Also downgrading the PHP version to like 7.0 may fix it.

Thanks! The host was set to 7.4... simply pointing to 7.3 instead resolved the issue.
