The Promotions AddOn was requesting to update to 1.0.17p. We are currently running version 5.0.11p due to the Paypal issue for non-profits that is not yet resolved (AFAIK). My site is now saying there was a problem and does not load. I disabled this addon and the site functions again.
How can I rollback to a prior version of Promotions AddOn? The only version available is the one that is not functioning with EE 5.0.11p.
