I have 3 different PHP scripts that talk to my database associated with this account and 2 of them work perfectly fine. The last one is getting blocked by CORS for some reason.
As far as I can tell it is set up the same way as the other two and is a simple MySQL insert query, not sure why CORS would have anything to do with this.
Odd, it seems the file name tracker.php is blocked on that account. You said there are other accounts on which this same code does work? Is the script also called tracker.php on that account?
