Thanks for the feedback — that’s helpful.
The free scan uses the public WPTide index, which currently reports PHP compatibility up to 8.0 so sites still on legacy stacks have a baseline check. For PHP 8.1/8.2/8.3/8.4 (and vulnerability insights), our Pro scanner runs an extended analysis via the CompatShield Portal.
I hear you that newer PHP versions matter most today. We’ve updated our messaging to make this clearer in the plugin and readme. If you’d like 8.1+ results on your site, I’m happy to run a complimentary Pro scan for you — just DM me and I’ll set it up.
Thanks again for calling this out and helping us improve.
