Cache issues

[flynnkd]

One of my players is having a problem getting into a new D&D5e campaign we have just started. One other player has had no problems so far.

His error message is:
21770

We have deleted the cache, but when he goes back in it starts doing the error again.

Any ideas what may be causing this?

This looks like the player has access to a module meant for GMs only and it is overloading his instance of FG.

Restrict access to modules only meant for players.

Then get the player to clear their cache (again), connect to the GM and see if they have any further issues.
