 * Hi, thank you, when I go to WP Simple Booking Calendar in the sidebar dashboard,
   I do get this error: There has been a critical error on this website. Please 
   check your site admin email inbox for instructions. + I am unable to access the
   calendars. This happens if I run PHP8.0, when I revert to PHP7.4 the issue goes
   away, i have no other issues with php8 on either front end or back end

 * Hi Roland! Thanks for your quick response. I have noticed that I had a different
   plugin similar to this. So I will have too look into this on other places. Thanks
   anyway!
