VASSAL had an internal error

I was waiting for the Mayday module, version 2.1, to finish loading.
Unable to attach the log file - forum interface says “The extension is not allowed”. (What extension? :confused: )

First few lines of the log:

See this thread:

At the moment there are only test builds with support for Java 11, no official release yet.

It’s the fault of our current hosting provider. Lunarpages has been nothing but awful every time I’ve had to deal with them. We were almost ready to move to our new site (hosted on our own machine, elsewhere); the current problem I think will hasten the move, I think.
