-No, it is 3.5 not 3.5.1
-The installation works fine as i can get into the members and activities and such.
-I have deleted the files and pages associated wtih BP and reinstalled. Still nothing
-i have run it as the only plugin installed and still the same.
I believe what is wrong is the permalink structure. When i look at the permalink options, they are all listed as http://www.website.com/index.php/2013/02/sample-post/ etc. I have tried to install BP in another place and it works fine but in looking at the permalink structure, it is http://www.website.com/2013/02/sample-post/
The site I am trying to get working is in a windows environment with IIS and the working version i mentioned is xamplite.
Is there a problem with the BP and the permalink structure having index.php in it?
