Help! Error message during checkout


Recommended Posts

I installed a contribution to add an additional shipping table. I was able to go through a test purchase, got two shipping options during checkout, but during the final checkout, I get the following error message:


Warning: Cannot modify header information - headers already sent by (output started at /home/thesav2/public_html/catalog/includes/modules/shipping/table.php:202) in /home/thesav2/public_html/catalog/includes/functions/general.php on line 29


What does this mean and how do I fix? I am a newbie so go easy on your answer :)

The error message means that some HTTP HEADER information (such as cookie) is being sent to the window, but some raw html content has already been sent (Maybe an error message...).


Try putting this at the top of the script and checkout what's happening:




This will print all errors to screen, try to spot what's happening before the error message.

I have/had? this same problem too

but i seem to not have the complete file. It appears to be ending at line 893 with no end to code

is there a problem with certain file lengths? - not appearing on the screen?


I have been viewing them in my hosting file manager - copying them to my edit program - altering and then reuploading - but this file only seems to show some of the file.


When I have reuploaded it, the file has reduced in size from 44k to 31k?


is there somewhere i can go to get the complete file?


thanks to all you clever people who may help me out there
