Hi Jason,
Sorry for the delayed response. My website is having a few e-mail issues that I can’t find time to fix. Really annoying. Sorry.
I’m running MSTW League Manager 2.10 on PHP 8 on my local test box. If it does you any good, I can give you a beta of that (off the top of my head, I’m not certain how many changes were made from the released version on WordPress.org).
I’ve not had time to fully test the Add-ons. I hope to get to it soon.
