blank screen/template override not working

Hello,
My template override doesn't seem to be working correctly. I initially installed zen cart locally using xamp, customized the design and layout then transfered over to a server. When I did the transfer there was an issue with the template override not working. All the changes I did in the languages folder were not being recognized under the name of the template folders I created. So I had to redo all the changes outside of the template folder I created.
Now I'm having an issue when I have only one product activated for a category I get a blank screen and when I'm viewing a product and I hit the "add to cart" button I get a blank screen. I installed the debug error logging utility and got this message:
[23-May-2010 15:52:30] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/thechoco/public_html/shop/includes/languages/english.php:703) in /home/thechoco/public_html/shop/includes/init_includes/init_templates.php on line 78
Could there be a connection between the blank screens and the template override not working?
thanks
Tre

You do not appear to have english.php altered/overidden

/includes/languages/english.php:703

See what line 703 in that file states

Thanks for your response Kobra,
Line 703 states nothing. The english.php file only has 702 lines.
I trouble shot the default english.php file and my template override english.php file and the default non overriding template english.php file is the one being used. Any idea how I can fix it so that my template is being activated. I checked in my admin under template selection and the template "Chocolate" is activated.

Download this chart and print from the Free Software Add On section..

It shows the override structure perfectly

What text editor are you using to edit the english.php

If you edit that file in a good Text Editor, you can remove the space(s) and/or blank line(s) from the bottom of the file after the closing php bracket ?> to fix this error ...
