Steps To Reproduce

Occurred after update to plugin today, both before and after update from WP5.4 to 5.5

Platform

Sermon Manager Version: 2.16.1
WordPress Version: 5.4 and 5.5
PHP Version: 7.3

Any Additional Info

Just did the normal plugin updates before main WP update and cleared the cache and the above error appeared.

Had to rename the sermon-manager plugin directory to get back into WP. Then did the update to 5.5, and renamed the plugin directory back to normal and reactivated, but the error is still there.

The file it complains about not finding is present.
