Warning: session_start(): Cannot send session cache limiter

[developer_x]

I had to add a new field to the admin/customers.php page. After doing that, I refreshed the page in my browser, the new field was displayed correctly but I got this warning at the top of the page:


Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\web\catalog\admin\customers.php:1) in c:\web\catalog\admin\includes\functions\sessions.p hp on line 67

I continued to get that error for some time even after removing the code which I had used to make a new field.

Any help would be greatly appreciated.

On line 1 of customers.php, you have entered a character before the opening php tag, either a blank line or something else. Delete it.
