Version 3.15.2 PayPal issue

Installed 3.15.2 and now PayPal throws HTTP 500 error. 

This happens when Process Registration is clicked. Browser is Chrome; no message on Firefox.
 

Hello

Guess you are using an older Joomla version (maybe 3.9.0 or 3.9.1). I detected the issue earlier today and fixed it

Please access to My Downloads menu item, download latest package of Events Booking, upgrade it to your site, then check it again. The error should be gone

Or better, update to latest version of Joomla 3.9.27 if it is possible (the error would happen if you are using Joomla older than 3.9.7 if I remember correctly)

Tuan

Thank you for the quick response. We are in the middle of registration for our event. Ran into two errors with installing the downloaded 3.15.2:
JInstaller: :Install: Can't find XML setup file.
Unable to find install package

Hello

Look like you forgot to unzip the received package before installing? See eventbookingdoc.joomservices.com/getting-started/installation for instructions

If you need help, submit a support ticket so that we can install it for you

Regards,

Tuan
