Fatal errors in plugin developmen

Are real people actually using your plugin? I just see the number of downloads, but it’s not clear how many people actually use it. And seeing errors gives the impression that no one is working on or using the plugin.

I spent 4 fucking days trying to find a design error and your support here and by email sucks.

Briefly speaking. Error. When I delete the demo Listing Types and create my own Listing Types, the entire design falls off. This problem occurs on 4 different sites.

How to fix the problem with Listing Types?
