When starting smartCARS, you get an error that says data parsing could not be done properly, similar to this:
1. Verify that you have at least 1 airport and airplane in phpVMS. Once done, restart smartCARS and see if the error still occurs.
2. Verify the integrity of the webscripts. You can find out how to do this here: Verifying smartCARS webscripts
3. Make sure your php version is set to 5.3.
If none of these solutions work, please open up a ticket with us, and we will try and resolve the issue.
