We have the Pro version of Easy Appointments. Connect Beta isn't working. From within the website, when we go to Connect Beta, it doesn't go to the menu. Instead, we get this message: "There has been a critical error on this website. Please check your site administrator's email inbox for instructions." But we can't connect calendars. Appointments are booked, but they don't reach the employee or the end client. The WordPress version is 6.0.11. The PHP version is 7.4.33. I've attached this PHP information: https://www.arfincaraiz.com/phpinfo.php
What can I do?
