1. You should not have error logging on a live site - it is a security risk.sidclel wrote: ↑Sun Aug 10, 2025 1:06 amAnother mistake is if you delete the dollar currency it gets full of errors

2. It is only a warning - it is due to php 8 upgrades.
3. The error is because USD is not defined. If you have deleted it - it is not defined.
Search google for
a. php8 Undefined array key
b. php8 Trying to access array offset on value of type null
DISCLAIMER:
You should not modify core files .. if you would like to donate a cup of coffee I will write it in a modification for you.
