4 years ago As mentioned before, no HTML is allowed before "session_start()". Make sure there are no blank spaces or any other output before your session_start function
By reading this error message
Warning: Cannot modify header information - headers already sent by (output started at /srv/users/l5k2e/apps/l5k2e/public/customer-system/customer-system-header.html:1) in /srv/users/l5k2e/apps/l5k2e/public/customer-system/login.php on line 37".
I can see that you are outputting "customer-system-header.html" before your session_start function. So re-order your code to always do the php first. Not have HTML first!
You are putting HTML on the screen right there, so re-arrange things so that does not happen.
When you turn to the login page, there is "Warning: session_start(): Cannot start session when headers already sent in /srv/users/l5k2e/apps/l5k2e/public/customer-system/login.php on line 33

I tried to change the location of session start, I don't know why. The same coding can run my other system. @jslemmer . PS: I updated the new login.php on Github. because I cannot update on issue. And there is link: http://l5k2e.instantcloud.cn/customer-system/login.php.
