GZip Compression Disabling Issue

[AlexT]

My website has been working happily with GZip Compression enabled for over a year, but when I tried to disabled it the website stopped working ... Namely, it produced a clear screen with

Warning: Cannot modify header information - headers already sent by (output started at /home/matrecom/public_html/includes/languages/english/modules/shipping/bd/table.php:57) in /home/matrecom/public_html/includes/functions/functions_general.php on line 44

Enabling GZip Compression fixes this, but it must be something really wrong with my site to produce such an error! What would cause it and what would be required to fix it?

Many thanks,
Alex

Never mind - this is now fixed. Sorry for taking up bandwidth with silly questions: an empty line after ?> in table.php at the end of the file was causing the problem. I wonder why this was not an issue with the Gzip enabled?

Thanks for the update and posting the solution was just one of those silly ol' space(s) or blank line(s) after the closing php tag at the bottom of the file ...
