Sandbox System Builder 9.1 not working on Forge, but works locally

After the update to 8.6 (Foundry) and the update to (9.1) Sandbox System Builder, I can’t get the latter to work. I can’t rebuild my character sheet template (the button simply doesn’t work), and the Data-tab on my actors are gone. I have tried uninstalling and reinstalling the system, but sadly it didn’t help. I have also created a new world in Foundry, and tried to see if that would make a difference, but it didn’t.

The system (Sandbox System Builder) works locally, but not via Forge.

Is there a way to fix this?

Thanks in advance

…I just tried to export my world and run it locally, and the Sandbox System Builder system runs perfect. There seems to be some issue with the system when running a world on Forge.

This sounds like an update issue, or a module class issue.

While you’re having this issue, I would recommend trying uploading your local version of the system.
