Hi gerikoenig, I’ve pushed a minor Plugin update for Custom Fields this morning as there was a problem with it.
Regarding Checkout Manager Pro, please de-activate the current Checkout Manager Pro Plugin and install the free Checkout Manager Plugin as the Pro Plugin is no longer maintained since the change of ownership (all of the features and data of Pro is now in the free Plugin), see:
