I've started creating a simple 'popular products' module for Opencart 2.3 just to get to grips with how to create modules in Opencart.
I'm having an issue where when I click to install the module from the extensions section in the backend I'm faced with an internal error page, some of my logic must be incorrect but I'm not all that sure where I'm going wrong. I was wondering whether anyone would be able to point out where my issues lie?
The module was intended just to be used on the default theme. I have labelled what files are what at the top commented out:
