Description
serg wrote elsewhere:
Conditions under which online alter works are getting more and more complicated, lots of cases will disable online mode. Perhaps it'd make sense to issue a warning of why exactly online was disabled? Otherwise, I suspect, users will be hardly able to navigate this maze of conditions.
So far this extra diagnostics has not been implemented, error messages still look the way they did before:
