These two issues might have something to do with customization StackIdeas did for us.
ISSUE 1: Ask a Question button
1. Select a post. The URL is correct.
2. From the post page, click the Ask a Question button. The URL is not correct.
The button automatically adds the category of the post in focus to the URL which, of course, creates a 404 error.
ISSUE 2: "index" added to main page
1. Log in
2. Open a post
3. Log out
EasyDiscuss adds "index" (not index.php) to the url. There should be nothing added to the url on logout.
Thanks for your help.
