Using ExpressionEngine Version 2.1.3 Build 20101220 running online.
My work system is winXP - No problem seen with IE8, Opera, Chrome, Safari
With Firefox, can log into front end of the website but not the control panel.
When I try to login… no error message… just returns to login screen.
This is in my config file:
$config['cookie_domain'] = ".my_domain.com";
$config['cookie_path'] = "";
$config['cookie_prefix'] = "";
$config['admin_session_type'] = "c";
$config['user_session_type'] = "c";
$config['require_ip_for_login'] = "n";
$config['require_ip_for_posting'] = "n";
$config['secure_forms'] = "n";
$config['multiple_sites_enabled'] = "y";
$config['allow_extensions'] = "y";
I bet it’s something silly
