If you’re having problems with FSACARS (including double’d flight codes (VMAVMA1100)), you need to create a log and send it to me:
In version 1.1.430 and later, in your local.config.php, there is a value:
Config::Set('ACARS_DEBUG', false);
Set this to true, and also, create a “log.txt” in /core/modules/ACARS. Make this 777. After a flight, post that file to this page (in a zip file, as an attachment)
