[softwarefreak]

Ask them to enable cookies in their browsers or add the constant SID along with yours urls

for example

header("location: /home/?action=main" . SID); 

[ori]

yeah looks like cookie issue

[Pablo]

so if i add the SID constant will that work cuz am using md5 hashed session and hiding the session id with $_SESSION

Added after 3 minutes:

well i add the SID constant i login it with no prob as usual but idk if it works for them

[softwarefreak]

but idk if it works for them

Disable your cookies from the browser settings & check!
