My Mautic version is: v2.15.3  
My PHP version is: 7.2  
My Joomla version is: 3.9.14  
My Mautic-Joomla Plugin version is: 1.0.0

**Your problem**  
My problem is:  
I’m getting the following Error trying to Authorise from the Joomla Plugin:  
Error: The site is currently offline due to encountering an error. If the problem persists, please contact the system administrator. System administrators, check server logs for errors code:500

These errors are showing in the log:
