My script is running several times, and I don't know why
I store payment information in a PCI compliant database, and wrote a script to process transactions monthly. This has worked properly for several years, but in the last several months when I run the script it tries to process every card 3 times!
Luckily, the Auth.net system properly blocks the 2 duplicates! But I can't figure out why my script is trying to run them more than once.
