Issue: 

After installing the extension on Production mode, the configuration page of the extension on the Backend shows 404 http://prntscr.com/mtbpsv

Solution:

You could refer some notes from us below:

1/ Please check if your site is on Production mode, after installing the extension, you should run di:compile , then flush cache to generate code and dependency injection configuration. 

2/ Or you could reset up extension: remove module version in setup_module table on database and rerun upgrade

3/ Please check our installation guide, please make sure you have named the folder correctly https://bsscommerce.freshdesk.com/support/solutions/articles/19000098942-general-installation-guide-for-magento-2-extensions
