Everything was working just fine until we updated to the most recent version of wpforo (2.2.4)

It seems that a major fatal error stemming from the cache file is conflicting and/or preventing recurring subscription payments to run. We're running PHP 8 and latest version of Woocommerce (8.3.1)

Below is the error:
