issues with first zencart store (white screen?)

hello there,

im new to this wonderful world of zencart/coding..

i have been messing around with zen cart and added modules for a few weeks now and started to piece together all the modules i wanted to use and make my own store... (easy right??)

well now i have a custom store: http://surfacedisinfectant.co.uk/

not live yet, however i keep getting glitches like..

sometimes when i search for something in the search_header it will just give me a blank screen, sometimes works. usually works if finds that word otherwise will just return a blank screen.

other thing.. when i add a product to the cart via the buy now button.. again the white page. but if i click back the item is added.. also same thing if i go to check out with something in my cart...

This white screen is annoying me now and i dont know what to do. i have tried re tracing my steps but i dont know what im doing wrong.. any help/suggestions?

thank you in advance :)

Especially the Debug Utility part.

ok.. so i done the debug thing, and on one of the pages i get this error:

[19-Mar-2009 23:08:21] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/disifin/public_html/surfacedisinfectant.co.uk/includes/languages/english.php:1401) in /home/disifin/public_html/surfacedisinfectant.co.uk/includes/init_includes/init_templates.php on line 78

im assuming its the same for the other pages that seem to give me this white screen..

is there something simple that i am doing wrong?

thank you! :)

The first referenced file is the culprit and spawns the rest or the errors - english.php:1401 as this file only has about 700 lines and the 1401 references line number it is most likely corrupt.
Look for additional spaces & or lines after the last entry "?>" and use only a plain text editor or a code editor to edit these files

Might be a bad assumption
