pmpro plugin malfunction since last update

Hello! This plugin has now been deleted for me by siteground because I was not able to access my site and only got this error message. Since the last update it seems to be conflicting with orbit fox. (I know it makes sense to go Plus with pmpro for support but the site is not running yet so don’t have any subscribers to cover the cost. But I cant go live and get members subscribed until this conflict is sorted out.) Can you assist please?
