Hi there,

I've recently come across an error after doing some work on the site. Like an idiot, I got in a zone and forged ahead with a bunch of changes after backing up . Please help?

Here is my error message (the only one I'm getting):
[11-Feb-2010 19:11:36] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/pass4979/public_html/onlinestore/includes/languages/english/extra_definitions/blank_sidebox_defines.php:2) in /home/pass4979/public_html/onlinestore/includes/functions/functions_general.php on line 44


Can anyone help?

Best Regards,
Daniel
