No, it does not do anything related to multilingual which is strange, however, I was able to fix the installation/swap by removing all the custom code I have for this package, somehow it was interfering in this process.
I noticed that concrete has some problems resolving my custom classes in the package, I’m using the $pkgAutoloaderRegistries property to define them, and seems to work but the problem comes when it tries to resolve and autoload the parent classes i.e
Class Dog extends Animal <------ The autoloader cannot resolve parent classes
Here is how I defined them
This is not happening in Concrete 8.x. I’m wondering if this issue has to do with the way I upgraded Concrete from 8.5 to v9
Any ideas on how to solve this will be appreciated.
