Edit Orders Installation Error

I just installed the Edit Orders module (version 1.5.3) and got the following two errors:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /domain/admin/orders.php:1) in /domain/includes/functions/sessions.php on line 108

Warning: Cannot modify header information - headers already sent by (output started at /domain/admin/orders.php:1) in /domain/admin/includes/init_includes/init_templates.php on line 36

I completely reinstalled it in an attempt to fix it, but I was unable to fix the problem. Any ideas? I'm using Zen Cart version 1.3.8a.

I found the problem. Of course the solution was easy, but it took me forever to figure it out. For some reason my orders.php file got screwed up when I edited it on my computer and uploaded it. When I edited it online (which is rediculously slow with my host) the problem disappeared.

I highly recommend you update to version 2. See my signature. It is free, just change the options to the free ones and go through the checkout. Enjoy Edit Orders!
