*#-BUG-#* Blank screen after submit of anything.
duckxtales - May 11, 2007 - 21:10
Hi,
I'm having a problem whenever I submit anything either updating or making an edit to an entry it goes to a blank white screen. What could the cause of this be?
Thanks,
pat
Blank screen common cause - PHP memory limit
Hi Pat,
The first thing I would check is the memory limit for PHP. Your host usually sets this and you may need to ask them to increase the memory limit for your domain/account. Sometimes you can change it by adding a setting in your .htaccess file. You can check what the limit is yourself by creating and uploading a file named something like "phpinfo.php with the following code in there:
<?phpphpinfo();
?>
Then point your browser to that file like: http://yourdomain.com/phpinfo.php
Then look for a line that says:
memory_limit 32M 8MIf the number is very low then that is likely the problem.
Check your Drupal .htaccess file in your root folder for the following lines:
# Override PHP settings. More in sites/default/settings.php
# but the following cannot be changed at runtime.
# PHP 4, Apache 1
<IfModule mod_php4.c>
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value session.auto_start 0
</IfModule>
# PHP 4, Apache 2
<IfModule sapi_apache2.c>
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value session.auto_start 0
</IfModule>
# PHP 5, Apache 1 and 2
<IfModule mod_php5.c>
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value session.auto_start 0
</IfModule>
And change it to something like this: (the memory_limit is the important one and the others are in cause you are uploading large files. Feel free to change the number higher if needed)
# Override PHP settings. More in sites/default/settings.php
# but the following cannot be changed at runtime.
# PHP 4, Apache 1
<IfModule mod_php4.c>
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value session.auto_start 0
php_value memory_limit 64M
php_value post_max_size 20M
php_value upload_max_filesize 10M
</IfModule>
# PHP 4, Apache 2
<IfModule sapi_apache2.c>
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value session.auto_start 0
php_value memory_limit 64M
php_value post_max_size 20M
php_value upload_max_filesize 10M
</IfModule>
# PHP 5, Apache 1 and 2
<IfModule mod_php5.c>
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value session.auto_start 0
php_value memory_limit 64M
php_value post_max_size 20M
php_value upload_max_filesize 10M
</IfModule>
I hope that helps,

Thanks Alian... I adjusted
Thanks Alian... I adjusted those 2 things and it still doesnt work. I changed mem limit to 32M and adjusted the htaccess file, but I still get a blank white screen after I submit any kind of form... what else can i do to diagnose this problem so i can show u all?
Another source of error is editing core files and/or theme files
All (most) core files and theme files are saved in UTF-8 format (2 bytes per character). If you edit on of these files with an editor that does not handle UTF-8 and especally if the file starts with
<?phpthe odds are it now has "unexpected" characters that cause problems.Blank Spaces
Good point duckxtales,
For me the problem was a blank space in my template.php file after the last ?>

THANKS ALOT!!!!!... this
THANKS ALOT!!!!!... this worked... it was the stupid Blank lines after the ?>
This would drive people nuts cuz of blank lines.... its hard to debug such a thing like this.... i hope this helps someone.. more keywords people might search for:
blank white screen submit submission
Phew!
I had exactly the same blank screen problem which was essentially down to the blank lines at the end of my template.php file. So thanks for posting this thread, I was getting worried for a minute
This will also happen if you
This will also happen if you have a blank line above your beginning <?php line.
Same here
Thanks for posting this. Seems like some extra spaces in the template file shouldn't break form submissions on your whole site, but it sure does.
