Well an issue with that is that you're running these on your forum with modifications and HTML errors; we can run a stock build with no alterations through an IDE (which their "AI" tool is) just like we did for the v8 release and glean details from that on our own.
Unless it's causing server errors in your web or MySQL server that we can walk through an actual log it's not really a report that we need as we could just read through suggestions from these tools on our own versus some of the fluff suggested (several of which are required resets for some browser compatibility).
Otherwise we're just having a coding disagreement with a bot that doesn't necessarily understand why code exists in the first place verses what is being produced in your environment (different PHP versions expect different coding standards and will work differently. ie php8 vs php7 and prior versions
UBB.threads 8.0 is compatible with PHP 7.x, 8.0, 8.1, 8.2, 8.3).
