All I *want* to do is enable "PHP Filter" at the moment. But the problem is if I try to enable another module it goes to a blank white screen at url "http://www.example.org/admin/build/modules/list/confirm" and i have to go back to "http://www.example.org" again in order to be able to access anything. Going to "http://www.example.org/admin" results in a blank white screen as well.

I've tried some Googling and to search these forums but they all seem to be issues using a php snippet. I haven't even GOTTEN that far yet and I'm already getting white screened.

Any ideas? Is there anything that can limit the number of modules you can have enabled? I tried enabling "Books" as well with the same result.

you probably need to increase the memory limit in your php.ini file.

It could be the number of modules you have installed but I doubt it. You don't really have that many enabled. Many times when I'm working on a Drupal site and I get blank white pages it usually is because php is throwing an error but the error message is being suppressed. Try adding the following two lines to your .htaccess file

php_value display_errors 1
php_value error_reporting 2039

It could have been a particular module causing you hassle.

Try and retrace your steps, to isolate which module may be causing the trouble.

You can disable modules manually:

http://drupal.org/node/157632

Mind which modules you disable. Like, don't disable CCK if you have fieldgroup working. (disable all CCK-dependent themes as well as CCK)... and I'm not sure if it's possible, but don't disable core modules either.

I had a white screen of death- and it was caused by a conflict between two modules. Both of which worked fine on their own, but when combined made a drupal-deadly combo.

So try enabling each module, one by one, and see where the error happens- to find your culprits.

Good luck!

All good suggestions but getting the error messages to show will point him to the exact line of code within the module that's causing the problem. Also, getting the error messages to show could save a ton of time later if/when it happens again.

hey, der, you should add your advice to the Troubleshooting Handbook page.

http://drupal.org/Troubleshooting-FAQ

Specifically, the one on the blank pages:

Okay first off, thank all of you for giving me a hand here. Second I did some digging around. Found a log full of pretty much just this line (few other minor things):

[16-Aug-2008 00:58:02] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 787099 bytes) in /home/phewson/public_html/includes/database.mysqli.inc on line 303

At least, its mostly full of that. The only other thing in the log is lines similar, but always different to this:

[15-Aug-2008 03:02:16] PHP Warning:  MySQL server has gone away
query: INSERT INTO watchdog
    (uid, type, message, variables, severity, link, location, referer, hostname, timestamp)
    VALUES
    (5, 'php', '%message in %file on line %line.', 'a:4:{s:6:\"%error\";s:12:\"user warning\";s:8:\"%message\";s:123:\"MySQL server has gone away\nquery: SELECT p.perm FROM role r INNER JOIN permission p ON p.rid = r.rid WHERE r.rid IN (2,7,8)\";s:5:\"%file\";s:50:\"/home/phewson/public_html/modules/user/user.module\";s:5:\"%line\";i:500;}', 3, '', 'http://badaxes.org/', '', '71.182.73.167', 1218787336) in /home/phewson/public_html/includes/database.mysqli.inc on line 128

Looking at my database.mysqli.inc file:
* Line 303: Just a blank line. Hit enter in notepad and you get the same thing.
* Line 128: Part of an If/Else statement:

trigger_error(check_plain(mysql_error($active_db) ."\nquery: ". $query), E_USER_WARNING);

So this looks like it could be a database error? I'd say its the PHP memory size, except for that is 32MB and none of the bytes involved seem larger than what is supposed to be necessary. Any thoughts, or is this strictly the PHP memory size?

EDIT: I think I should note that I cannot seem to DISABLE any modules either. I get the same results. This has me leaning on the db issue.

they are 2 separate issues.

WSOD (http://drupal.org/node/158043) is a memory issue in your case. Up your limit. You're using a lot of modules, and once you start adding data (esp. like picture processing), you're in for trouble.

mysql gone away - (http://drupal.org/node/259580). this probably has to do with huge blocks of information trying to be passed back and forth.

Looks like my suspicions were correct. New webhost so it took me a while to figure out how to do it, and I'm new to Drupal, but I did a check on my db. Found 2 sessions still open on watchdog. Did a Repair and PHP Filter was enabled when I went to Modules to try enabling it again. Looks like something was hung up accessing my database. No idea what as I've been doing a lot of changes in the last 2 days.

Thanks for the help all!
