We have recently moved our Joomla site (version 1.5.12) from a Hostgator dedicated web server running CentOS 5 with Apache 1.34 and PHP 5.26 to a Rackspace dedicated server running RedHat EL5 with Apache 2.2 and PHP 5.16.
Since moving the site, we have had intermittent login problems using mod_cblogin trying to login to the front-end of our Joomla site. Especially when attempting to login after a timeout expires the session, it's a pretty sure bet that the login will fail.
Even though the login fails, the backend (admin area) lists the user as logged in, but the user has no access to the front-end areas restricted to logged in users, and the login form remains active (as if the user isn't actually logged in).
I have turned off each module and plugin to determine if it is a conflict with no effect on the problem. I have upgraded the CB version to 1.2.2, and have attempted all of the suggested login fixes here in the forum (htaccess forcing WWW, turning off spoof in comprofiler, etc). The problem persists. Any assistance would be most appreciated. I would rather not disable CB and switch back to standard Joomla login.
