Running newest Magic Mirror, installed April 27, using Sam’s scripts.

I’m getting broadcasts as you can see, but default calendar and all modules that depend on it show nothing.

any clue what’s going on?

For exactly this situation. Trying a specific fix or all of develop branch.

If you use my upgrade script it will move you back to the mainline, or I’ll give you instructions

In PR #4180, I fixed that for calendar and other consumers.

Comment out these lines in calendar.js

It is multiple systems to one server, and still unsolved. Worked fine before “upgrade” to current MM version.

Can you explain the setup and config you are running.

Is this multiple systems to one server?

We added a caching handler to reduce unnecessary sends to the same module
