luceos I ran some more tests tonight ,but nothing seems to get this going. I used a .htaccess checker available here ( http://htaccess.madewithlove.be/ ) in order to check the output of the rewrite. Again, I am testing the url http://forum.yerbamateblog.com/api/users/1/avatar With the current .htaccess shipped with the download, the outcome is:
http://forum.yerbamateblog.com/-
It seems the rewrite with the authorization is just setting everything to - (dash)
When I comment out this line, I get:
http://forum.yerbamateblog.com/api.php
Additionally I get this messenger from the checker saying that test were stopped due to the L flag in the RewriteRule Options. So I removed the L and I still get :
http://forum.yerbamateblog.com/api.php
But unfortunatelly still getting the 401 Error. Does this help raise any other ideas of what might be wrong with the rewrite? I believe my issues is essentially the same as the one reported by nimbleton here:

Thanks for your help
