XF 1.5 Can't login to forum, but is logged in for addons

[TheLaw]

An odd issue on the new test server. This site worked perfectly on the old server (but that didn't have an nginx server deployed reverse proxy for caching.)

See https://aquariumspace.com as an example of where you can be logged in ONLY on pages other than the forumhome. Try user name fishyfishy and password Testing 111. The forum does not seem to keep a user logged in. But once you navigate to the gallery, articles and reviews section of an addon, that works fine and as expected. I'm wondering if others have experienced similar behavior.

PS - I'm using PHP 5.6, XF 1.5.3.

In the spirit of helping others troubleshoot, the issues on this new server were caused by nginx being used as a proxy server for caching. Once removed, this odd behavior is gone. So CloudFlare (see other thread) and nginx, together and separately, can create all sorts of confusion and havoc.
