HELP!! Blank pages when accessing shopping cart

[johnd2202]

Hi,
I am getting the following in my error logs and I can't access my shopping cart due to it being a blank page.

PHP Warning: Cannot modify header information - headers already sent by (output started at ......./public_html/includes/configure.php:1) in ....../public_html/includes/init_includes/init_templates.php on line 78

I know there are some cases of people having too many spaces but in the config file? I have a template installed, external images mod and was trying to implement the Comodo ssl seal image on the site. Your assistance would be greatly appreciated!

Your assistance would be greatly appreciated!

Does the problem go away when you revert back to the 'classic' template? If so, there is something amiss with your new template file(s). Did you edit them in any way? What editor did you use? It is possible/likely that your editor added a blank line at the end of the file(s) that were edited.

Cheers
Rod

Look at the file:
/includes/configure.php

What is on line 1 ... it should start with:
<?php

I have switched to the classic template and still get the blank page. I have also replaced the config.php file with a backup that I had and it still has the same results! Something in the header under one of my files is corrupt and I can't locate the culprit.

/includes/configure.php

<?php

I have double and triple checked this file and everything looks like it should. I'm a little confused on the blank line issue. How can you tell if there is a blank line? I don't think this is the problem but I'm curious to see if it might be.

Look at the file on the server and see if there is space(s) or blank line(s) before the starting:
<?php


on the file ...

Here is the code in the config file minus the passwords and such.

Below is another error in the cache folder in addition to the original. I really do appreciate your assitance in helping a fresher out with this issue. You guys are great!

Copy the file to your computer then open it in a text editor and see if there are any space(s) or blank line(s) before the starting:
<?php

If there are, delete them and reload to the server ...

[johnd2202]

I fixed this but unfortunatly I had to do a re-install from the backup site. I think I narrowed down the problem. The import images from seperate urls is the culprit in this instance. Somewhere in the editing of the files, something went wrong. I will test this theory on another test install to verify my thought process.
