We have a Joomla content management system (1.0). Users who use AOL and sometimes IE are able to register, but when they login to the site, the login is not taking effect. It is not a password problem, and I am unable to duplicate the issue, but many users are reporting the problem. I had one of the users try to register and login with a separate Joomla site, and it worked.
What should we be looking into that would effect AOL and IE users but not Firefox in terms of logging the user in? It seems to be a cookie problem, but since the secondary site worked, I do not think it is a security issue on the individuals computer. Both sites are located on the same server and are configured similarly, though not exact as they are different sites with different purposes.
Does anyone have some troubleshooting steps we can try to resolve this crucial issue for our client? Thanks in advance for your help.
