I've looked through about twenty pages of this thread and didn't see the answer, so I apoligize if this is a repeat.
I installed the latest version of this contribution and had no errors at all. Unfortunately all of my urls now resemble this:
I followed the instructions in the install.html file and everything went fine. The only thing I did not do was follow the instructions laid out in the additional_install_instructions.txt file included in the contrib. I didn't see any note or explanation telling me when I might need to use the additional instructions.
So, basically, what have I done wrong?
