Hi Brad,
Sorry for the late reply — I didn’t know that I don’t an email when there’s new support topics, so I just saw this right now.
First of all, I’m sorry that this has happened. The plugin does check for PHP7.4 or newer, as well as for a relatively updated version of WooCommerce and WordPress, but you seem to have both of those up-to-date on your site. Moreover, any activation errors should’ve been caught by WordPress recovery mode since WP 5.3, so this is very weird indeed.
The only thing I can think of is some sort of error with a 3rd-party plugin. If that’s the case, the exact conflict should be visible in the logs. Do you happen to still have them by any chance?
Looking forward to hearing back from you!
Best,
Tony
