Modules wont show

[FrontRunner]

I´m having some problems installing vbdrupal with vbulletin.

Problems:


Modules page is empty when i press the modules option in the admin menu
log shows: images/gradients/gradient_tcat.gif not found. (vb theme related)


This seems like i´ve done something wrong on installation. The following are the steps i´ve done:


Install vbulletin 3.5.4. in a folder named /public_html/forums
Run the install script for vbulletin (succesfully)
Install vbdrupal 1.3.2 in a folder: /public_html/forums/drupal
Import the product-drupal.xml file through the product/plugin menu(succesfully)
edit the config.php_new-file (in sites/default) to set $vb_dir = '/usr/local/www/gamestiq.com/public_html/forums'; and $drupal_dir = '/usr/local/www/gamestiq.com/public_html/forums/drupal';
in vbulletin->admincp i´ve set the Drupal URL to http://www.gamestiq.com/forums/drupal


Can anybody tell me what i´ve done wrong and why the admin/modules shows up blank

An empty module page is in issue produced by drupal.
What exactly causes these issues isn't known to me, but often restarting the webserver fixes this. Ofcourse this isn't a good solution.

[FrontRunner]

Hmm, not so good news...

Anything that can be done besides restarting the webserver (hosting is on a rented space so I dont see it happen that I can ask them to restart the server).

Have allready done a complete reinstall resulting in the same problem!!

Do you have many modules installed? Your PHP maybe running out of memory. Check the apache error log.

[FrontRunner]

No I didnt install any additonal modules, so far!

[elmuerte]

An empty module page could also because of a faulty PHP code. vbDrupal doesn't intercept critical PHP errors but it does disable the default error reporting.

[FrontRunner]

Well where do we go from here, reinstalling didnt work, how do I enable the default error reporting?

[elmuerte]

open common.inc and search for
set_error_handler('error_handler');




just comment it out (temporarily), e.g. put // in front of it.

[FrontRunner]

Commented it out, but didnt show any errors. Anything else we can think off? Could it be safe_mode thing??

[elmuerte]

no ideas left

Maybe this is a pathing issue.

What happens when you go directly to the URL:
http://www.gamestiq.com/forums/drupal/admin/modules

Also, when you click on the link to your modules, what URL does it take you to?

[FrontRunner]

Admin link goes to http://www.gamestiq.com/forums/drupal/?q=admin/modules

Both show up as empty!!

[sifuhall]

With no additional modules installed, the path is correct, and everything else seems to work I can't imagine what could cause this.

Are there any errors on your webserver error logs?

[elmuerte]

Well good new... on my test drupal 4.7 install I have the same problem, it doesn't contain any vbdrupal stuff, just a couple of my own modules.
Anyway, I have a broken environment to mess with.

[elmuerte]

Ok it's mostlikely this:
http://drupal.org/node/31819

still odd that my almost clean drupal 4.7 has that problem

[elmuerte]

Delving into this problem a little bit more.
Does your host use a php caching system like eAccelerator or MMTruck?

[FrontRunner]

Not as far as I know. Only Zend Engine 2 has been installed.

[elmuerte]

oh.. well increasing PHP's memory limit should fix the issue.

But currently I'm accusing eAccelerator from being broken, my clean drupal 4.7 was using 5M when viewing a simple page. After a server restart it was only 180k. Since your site doesn't run an php caching thingy it might as well be a drupal issue.

I had the same thing happen.

I have had "display errors" enabled in my PHP.ini
The first time it came up with a memory error, then subsequent times, it just had a blank page.

So I edited PHP.ini memory allowed from 8m to 16m and the Modules page worked.

Hope that helps

the main cause of this problem is too many modules in the modules folder

I originally removed modules from there and the modules page showed, I reuploaded all the modules (10 from the default upload) and the page is now blank

I shall begin to remove modules .. 1 by 1 until the page shows again

I only hope they are working to find a solution as this seems a serious flaw

Cheers

ps.. also increased ini memory to 16MB
update .. I removed 4 modules and the page showed again ..

[All4Data]

I am concerned about this bug and would like to know whether there is a better solution for this problem, please?

I found that once I enabled a few modules the modules page again went blank

Currently I am working my utmost to better understand drupal and its functions, however to have vBdrupal setup on my PC and then to go to the server and find problems occur is a problem

any solutions, please?

Thank you

Drupal simply uses a lot of memory, not much you can do about.
My site uses about 10MB on the frontpage. The module page uses 12,5MB
Apperently PHP's APC version 3 and higher doesn't reduce the memory usage as APC 2 did (or maybe version 2 faked information about memory usage).
