Updated Plugin Won't Allow Bookings

Any help here? Old events have stopped working too. Client is getting really bummed.

just to narrow down the problem and help us debug the issue is it possible to try the following temporarily:

– deactivating all other plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems

Yes, thank you. I actually tried that very first thing. I deactivated all plugins and theme and still had the issue.

You can see the problem at: https://academyofdes.org/wp/events/comprehensive-esthetic-rehabilitations-design-techniques-and-materials-by-dr-gerard-j-chiche/

The problem seems to be that access to admin-ajax.php is being blocked.

Which payment gateway are you using? If you’re using Authorize.net a valid SSL certificate is needed for transactions.

Duh. Thanks. You guys rock.

No problem. It should run without an SSL in sandbox mode (for testing).
