I just installed drupal 6.11 with hotspot-6.x-1.x-dev and CoovaChilli 1.0.13.
Everything seems to be working ok. When I open my web browser, I am redirected to the drupal hotspot module page but instead of getting the login page, I am directly redirected to a "Page not found" with an URL similar to http://www.myserver.com/badquery" target="_blank
Doing a few test with the URL accessed (taken from the log of the server), it seems that its the "uamport" parameter in the URL that cause this problem.
Is this caused by a configuration problem ? Any idee how to fix it ?
