Which version of bPermissions are you using?: 2.10.9

Which version of CraftBukkit?: (Please don't say "latest"!!!) git-Spigot-c46583f-e6f9fd4 (MC: 1.8) (Implementing API version 1.8-R0.1-SNAPSHOT)

Which OS? Windows 7 64b (local testing server)

Any other information we may need (plugins, configs, etc):
default world, world_nether and world_the_end

Please fill out this form properly! Failing to do so may result in your ticket being marked invalid.

Just a small note, newer (at the moment newest) version of Spigot makes no difference (git-Spigot-fa7cbf9-00eba53).

try 2.10.9b

Works, thanks. But seems to convert only world specific user files (in the respective world's subfolder), not the global one. Is this intended?
