So multiple pages and some updates later and a simple fix is not in the bug fix release. With this i mean the sister pool error due to a wrong location of a piece of code.
All credits go to
Black Xoul for this, but i thought i made it a bit more clear for those who still weren't able to fix it.
Simply open the index file in a text editor (wordpad or notepad c++ work well) and edit the following.
Cut and paste the red line in this spoiler, into the location in the next spoiler.
By putting that line between the first and second "endif" expressions you fix the entire code mess up, just dont forget the cut and paste, don't leave the text standing in its original place, cause that causes the break in the code.
Again, all credits to Black Xoul on page 2 for fixing this, just thought i would elaborate on the fix to make it easier to spot for people, because in the html file it isn't written the same as in his fix post.
