A few things have been going on since upgrading my vps from one cpu to two and the providers explained they had to set me up on an older kernel, something about my set up not compatible on normal kernel for upgrade.
Anyway just when the site has gone live and I'm out advertising it, I came back only to notice it keeps logging me out when I navigate around.
Somehow I think this also has something to do with upgrade and with my having a subdomain because when I did the upgrade my site.com was still loading but my drupal.site.com was not until they did the switch. Then I couldn't log in as admin so found the .htaccess file had recreated itself in my drupal folder with upgrade so I had to delete it in order to log in at all. It's a long story but in order to have clean urls had to do away with .htaccess and configure settings and httpd.conf instead.
I'm not sure what to do as the site is now live and I keep watching for member signups. At the same time if it is going to cause all sorts of problems, I want to fix them now before anyone joins.
My question is what could be forcing me to log out considering all of the above? the urls are all consistent.
