So I have two different extensions I've made. Let's call them E1 and E2.
Upload them is no problem.
When I go into my course, go to manage extensions:
1. Add E1, no problem
2. Add E2, E2 added BUT E1 removes itself
3. Add E1 again, E2 removes itself
Any adapt-contrib plugin doesn't have this problem, only the ones I've done myself.
Any suggestions?
