J-BusinessDirectory - 500 Internal Server Error on Front End

Hi, The J-Business Directory extension I just purchased installs just fine. I can navigate and use the administration fine. However, it creates a 500 internal server error on the front end. Nothing I adjust so far seems to fix this. Only uninstalling the entire extension fixes this issue.

Joomla version 3.6.5
PHP version 5.6.32

Thanks

Here is the error using error reporting. All pages show the same error: Fatal error: Class 'JComponentRouterRulesMenu' not found in /home5/certifm8/public_html/dev/components/com_jbusinessdirectory/router.php on line 67

Hi,

Please create a ticket on our store and provide us joomla admin access.
We will fix this asap.

Hi,

Please notice that the last release is compatible with Joomla 3.8 and above due to the new modern routing mechanism. 

This error means there is a problem on the server side. A Server Error can be caused by any number of things from uploading the incorrect file to as bug in a piece of code. This error response is a generic "catch-all" response. The web server is telling you that something went wrong, but it's not sure exactly what that is. If you have root access, you should review your web server's error logs to get more information about this. If you are using shared hosting plan, you should contact your host to get more information. The best way to debug the error depends upon the server and what's actually running at the time. Consider some debugging tips to help diagnose and fix common causes of this problem.

this is a big problem, anyone suggest a solution

Hi,

This is just a compatibility issue between Joomla version and JBD version.
Starting with JBD v5.0 it is required to have Joomla 3.9 for the routing mechanism.
