Biomes Of Plenty vs Cauldron

[ghost]

Currently renting a Cauldron server through serverminer. I have all my mods loaded in and working correctly, except for one: Biomes of Plenty. This is the error I got:

Missing Mods:
Forge : [10.13.4.1566,)

I know its obvious that I need that forge version, but the issue is I need to use Cauldron in order to use my plugins. I tried looking for help, changed the server properties and reverted to the old BoP versions, but nothing has worked. Some insight would be great!
