I am getting the following error trying to start up a PBF game. Marti registration and test were successful and all PBF fields have been double checked.


Mikawa released his ships to operate independently of his flagship, and at 01:31 he ordered "Every ship attack."
TrpleA PBF code still is not compatible with the newer/current forum software (NodeBB).
Don't always trust TripleA when it comes to rules questions. Know the rules before you start … and better check what TripleA has done.
@Panther Is there some workaround or more manual approach all the people currently playing games are using?

Yes. Just use Play by Email instead - and instead of sending emails just post the turn summary manually (copy/paste) and attach a manually created savegame.
You don’t need to setup the mail configuration.
