I've been searching for a solution to this issue for quite a while now, but I couldn't find anything that could help me. I hope someone here has better luck and can find a solution to this... Any help is greatly appreciated :)

Answer

Solution:

The solution to this issue was renaming the .pb-config folder to .bp-config. The tutorial available under this link has a spelling error and that was the reason for all the suffering...
