Hi,
I'm running on Docker in a VPS.
I was in 10.6.
In my development environment I had upgraded to 11.2 a while ago.
I tried to deploy a new version of the app to the VPS (10.6), and it told me I had to upgrade r3 version to be able to upgrade.
I tried to do so, but I discovered 11.2 is no longer available.
I did the upgrade to 11.5.

After the upgrade but before applying the new version of the app, something unexplainable happened.
The application took the header, colors, title, etc. from another application I have running on the same server (in a different docker container).
I know it sounds nonsense, as each application has its own database, and are on separate directories, but that is what happened.
Also the Configurations page in my user profile shows blank (no configuration at all)

I have other applications running on the same server, and none of those showed similar behavior.
After this, I tried applying the new version of the app (the one I had on development environment), and it applied the changes to the functionality of the application. However the UI customization remained changed, and the Configuration page continues to show nothing.
I would really appreciate your thoughs on this, and if there is a way to solve it (at least make the Configuration page show values again)
Thank you!
