Hi everyone - Evo 1.0.12
I have been getting the familiar old "
Cannot modify header information - headers already sent" error message and it is driving me crazy.
No white space before or after, Utf-8 with NO BOM - tried pretty much everything I could find online - PLEASE HELP.
*******
The full error message is - Warning: Cannot modify header information - headers already sent by (output started at /home/rsacours/public_html/assets/modules/coursemanager/process.cm.php:11) in /home/rsacours/public_html/manager/includes/document.parser.class.inc.php on line 3595
Error
(Note: The line number referenced here - process.cm.php:11 is the one following this line
below)
*******
I have a (Course Manager) module that manages some custom tables. One of the functions is to update/edit course numbers which works fine for the first row (red box in attached image) but for all subsequent rows the above error is generated.
Two files are involved here - 1.
process.cm.php which is called to process the POSTED data and 2.
index.cm.php which is the GUI for the Course Manager Module.
If anyone can spot the issue in the offending file below I would be eternally grateful.
1. process.cm.php
