Whenever I try to access http://www.atari-forum.com
with Pale Moon (a Firefox variant) on my Android tablet, I get a 403 "You don't have permission to access / on this server" message. Pale Moon's user agent string is "Mozilla/5.0 (Android; Tablet; rv:25.2) Gecko/25.2 Firefox/31.9 PaleMoon/25.2.1".
When I use Pale Moons "request desktop site" function, which changes the user agent to "Mozilla/5.0 (X11; Linux x86_64;rv:25.2) Gecko/20100101 Firefox/31.9 PaleMoon/25.2.1", everything is fine. Is there some sort of filter on the user agent, or can the problem be caused by something else?
If someone's looking at the log files, the blocked request should have come from the same IP address as this post.
