empty setting page + profile links to user-raw

I'm not sure if it's critical as my site function beside some functionalities of this modules but if I consider this module along, it's barely usable.

A couple days ago I upgraded from 6.x-1.4 to 6.x-1.5 (I did run update.php) with no detectable problem.

An hour ago I changed permissions to include anonymous user for access user profiles in user module. I tested it and http://dynv.qc.to/users/dynv showed in another, not logged in, browser. I realized a profile field wasn't right so I updated it and got an error message letting know that an email couldn't be sent to the administrator.

But when I clicked the view tab the change was done so no harm right? Wrong! When I reloaded the page as anonymous the page was not found. So I went back to the front page and checked for a promoted story to click on my nick and the link was now leading to http://dynv.qc.to/users/%5Buser-raw%5D that did indeed show the information I was seeking, including the update ; shown in the attached screen-shot. A problem I foresaw right away is what if another user post a story? Not likely to happen but still...

The biggest problem is that the pathauto setting page ( http://dynv.qc.to/admin/build/path/pathauto ) is now white and its source code is empty.

If things don't improve soon I'll have to remove user profiles access for anonymous because I don't want search engine crawlers to get erroneous paths.

Thank you kindly for your help.
