Hi everyone:
Thanks for the details in this issue, I will try the workarounds described above.
I installed phpvms 7 dev branch in a local delployment and worked perfectly.
However, when I moved this install to the hosting server and changed the details in the .env file for db, everything seemed to be working perfectly, except for the pulldowns for the airports anywhere on the site. Definitely is a "cross-origin scripting error because the local install with the subdomain "localops.virtualairline.com", works just fine.
I've changed last night the APP_URL to reflect the new URL name, I will check today after clearing the cache if this fixed it.
Also, I've imported a list of all airports in the world, I think there are about 14k, and if this affects negatively in some way I will replace it with the list published by filipet
Thanks!
UPDATE: Just fixed- I've validated that the APP_URL was the correct one, and as we are forcing all connections to Secure (https), also validated the APP_URL says https://ops.airline.net for example and not just http://, and cleared all the caches, views and application, this just fixed the airport dropdown list issue.
