Hi Dave,

I took your php error logging suggestion except I directed the output to a file instead of the screen. That turned up the following: 

PHP Fatal error:  Cannot redeclare image_help() 
(previously declared in /var/www/html/modules/image/image.module:7) in 
/var/www/html/modules/image/image copy.module on line 7

Which was of course caused by a duplicate image.module file that I missed. Thanks for this tip - if only it hadn't been such a boneheaded mistake :-}

Would recommend temporarily setting your php.ini to show errors and warnings to the screens to determine if there is an error being thrown before enough of the drupal logging api gets started, and try and hunt the error that way.  Also make sure the instance is set to log the errors to the screen.  After doing this, make sure to do a view page source to see if a php error isn't being thrown in the html header.
 
This is a wild shot, but I would also check to make sure that you can't navigate to the page dircectly (not using clean urls, but index.php?q=admin/modules. This would potentially eliminate a mod rewrite rule overriding your page load.
 
Dave

Subject: [support] Blank Modules Page but Not Memory Related?

Hi,

I've run into a puzzling behaviour on two separate Drupal installation hosted on virtual servers by the same company. One is a 4.4 installation hosting a single domain; the second is 4.6 and hosts several domains. For some reason, both installations suddenly no longer display their modules page, although the sites are functioning normally in all other respects. 

I went over http://drupal.org/node/31819 (My admin > modules page is blank). On both sites:

- I checked the access and error logs and no memory errors were evident
- I tried Firefox, Safari on OS X and MSIE 6 on WinXP (same behaviour on all)

On the 4.6 installation:

- I increased the memory limit from 8M to 12M via php.ini, .htaccess and /sites/default/settings.php (no change). I went as high as 128M using php.ini, still no difference.
- I deleted then restored each contributed module one at a time (no change)
- I ran the Repair Table command via phpMyAdmin on all tables for all sites on the 4.6 installation (no change)

The host company says nothing has changed recently at their end (Apache/1.3.27 (Unix) (Red-Hat/Linux) PHP/4.3.10)I'm at a loss as to where to look next - any pointers would be most welcome. TIA.
