To my knowledge, no one has Ace'd AdvancedBagsPlus.
To that extent, if you are having errors for that addon, seeking out the author of ABP will be best for resolution for your issues.
To answer your generalized question of addon conflicting, YES! A resounding yes! Addons that call upon the same action and modify the results of such an action have a high probability for conflict. I will not try to cite specifics to your example as my understanding of errors is limited, but I would investigate the use of two addon that modify, change, or call upon the container buttons. Perhaps that will offer some minor insight for you.
