after login, screen is blank

when i remove a Module i installed, it works fine. but when I enable that custom Module again, it even
shows a blank screen after the Module is enabled. The module list does'nt get showed. when I go back manually
from browser's navigation bar, following is the error i see (although site and module is working fine)

warning: Cannot modify header information - headers already sent by (output started at /home/www/waqarwebsolutions.awardspace.com/portfolio/cts/modules/customer/customer.module:1) in /home/www/waqarwebsolutions.awardspace.com/portfolio/cts/includes/common.inc on line 313.

BUT ...... once i log off, then again when i login, ------ BLANK screen again....
So when i delete the custom module from modules directory, i'm able to login again.
There's something in the custom module that's bugging.. but what? because its working absolutely
fine on my local server. but is not working on the url i mentioned above thats my testing server on the net.

Okay I seem to have found the solution to my own problem.

The file got saved of type UTF-8. I saved it again as ANSI type and ----- its all working fine now. Spent hours on this. hope this helps someone save time.

hey there!
thanks, i've had devel, project, project_issue, codefilter, sioc, comment_upload and cvs_log modules installed, i dont know why but once i removed them (rm -r -f from console) then the site works fine. i guess maybe it has something to do with downloading them on windows and transfering them through mount.. i don't know. but your tip was very helpful so thanks a bunch!
----
so i've checked again and the problematic module was devel.

This helped me.

Same problem exactly happened to me. After submitting any form including login a blank page resulted. All I had done was edit the template.php and the theme-settings.php files and apparently were saved in windows text format. I use HTML-Kit. So I changed the save settings to use unix format and resaved the files and Wha-la everything worked again.

After inserting function

After inserting

function phptemplate_preprocess_node(&$vars) {
$vars['template_files'][] = 'node-' . $vars['nid'];
return $vars;
}

to template.php, Drupal 6.6 went off the hooks in Safari with the error CFURLErrorDomain:302 on any page. In IE all works fine as long as login is not concerned. After logging in site crashes in IE as well. Disabling template_preprocess() in theme.inc allows login in any browser, but no theme is applied.

Checked:
- Memory
- File encoding
- Tags
- All changes were rolled back

The problem still exists

Blank Space in template.php

I Just had a similar problem while moving a site from Dreamhost to OVH. It turned out the White Screen of Death was being caused by three blank lines at the bottom of template.php after the ?> tag. I deleted them and like magic the WSoD has dissapeared.
