Ok did more debugging, what looks to have happened was that our pro version which was something like 1.4 somehow was able to auto update to 5.09 and in doing that partially imported the buttons into the v3 table (81 of 309) and then everything went to hell as v5 isn’t php 7.3 compatible
Not the best fix but as I don’t have coupons applying to subscriptions just 1 time purchase of setup fees I just replaced the code with = false instead of doing the function call.
