My installation is on a Fedora Core 3 Linux machine with Apache 2 and PHP 4.3.9 and Postgres 8.0.3.

I have followed the install.txt instructions.

The Database wa created from the script with out error, I granted the requisite permissions on both Database and on the directories where I installed Drupal.

I made the alterations to the settings.php file, to base URL, and Database.

But all I get when I point my browser at drupal is a blank page. Nothing happens and no erros occur either.

If I edit the index.php file in the drupal directory to include something like phpinfo, the expected configuartion is returned, so I ma a real loss as to what is going wrong, amd the lack of any error message or even notification makes figuring out what is wrong very difficult.

Cheers

Performed a windows installation with IIS and PHP 5 but the same Postgresql Databse and all works like a dream.

Would still like to get this working on Linux though so if anyone has any ideas ( perhaps a php.ini setting or something I should be configuring in Apache ) I would be appreciative.

The absence of any error messages makes the problem difficult to debug.

I was getting just this problem when I was trying to load too many modules. Although one would think that the default module set wouldn't cause any problems, it may be what's happening here. Are you trying to load any of those large modules, like flexinode, etc.?

samwilson -

As the Linux installation is not letting me get as far as the administration page where I can turn modules off, what file do I neeed to edit to test your theory by preventing Modules loading.

Or can change PHP's behaviour? The machine I am trying to do this on has 512 MB of ram if that helps.

This is just a shot in the dark, but I have found that text encoding issues can sometimes be the cause of a blank white screen, or mangled code of some sort that just "throws" Drupal into the white zone. This happened to me when I tried pasting a patch into what I though was a plain text document and uploading.

What I've taken to doing is using BBEdit and creating an empty html document and then overwriting the deafult html codes. There are differences with with invisible characters like line feeds on different platforms that need to be watched out for. Also, editing code and introducing unintentional errors if you don't know what you're doing can send the system into the white zone too.

Try and retrace your steps in terms of what you were doing/modifying before this happened.

Remove some modules from the ~/modules directory, prehaps moving them to a new directory called ~/modules-disabled? (Where ~/ is the directory that you've got Drupal installed in.) It doesn't matter whether a particular module is enabled in the administration section, Drupal has to load certain bits of all the modules, regardless. To start with, remove modules that you're not going to need anyway, like legacy.module (assuming this is a new install and you have no need for legacy features) and others.

Hope this helps.

Sam,

this fixed my issue - for me it was the G2 (gallery2) module.
Wish i'd have seen your post a few weeks ago when my problem first started up ...

Thanks,

marco

I have had the same problem when I transfered a completed site from windows to Red Hat. The problem always turn out to be from partial uploads of the site. I have to check that all the files in each folder have been uploaded. When I re upload everything folder by folder everything workd OK. Especially check includes folder.

Hi there,

I'm having the same problem with a blank screen and no error info too. However I added debugging to the index.php before and after the drupal functions to test the time taken to execute the script.

It did load up after an hour....

If I repeatedly refresh it loads up every now and then. Other times it takes a few seconds, most times it just doesn't load up (well I didn't have time to wait)

Has anybody managed to figure out a solution? It's very frustrating!

Bryan,

how did you add debugging to the index page?

Thank You,

Re-naming the sites/all/modules folder to something else allows the update.php page to load, then bring over the mobules one by one until you have everything working again.
