"Access control" page not displayed anymore

By drumming_cat on 11 Mar 2009 at 02:33 UTC

Hi,

I currently cannot access the Access control page from the admin menu anymore, i.e. the link:
https://example.com/admin/user/access

IE returns Cannot find server - The page cannot be displayed.
Firefox returns a white page.

I have no trouble at all access all the other user management pages.

Unfortunately, I have no idea which installation / changes / updates might have caused this issue (I hadn't used the access control page in a while, however, now urgently need it...).

My drupal installation profile is:

Drupal 5.16
MySQL 5.0.45
PHP 5.1.6
Web server Apache/2.2.3
SSL activated

Thanks in advance for any help,
cheers,
Tash

How About...

How about if you go to the admin page (site.com/admin). You can access your user settings/management from there. See if that works. If so, you can accomplish what you need right now. Once you have the time, you can search for what changed the page. Check for recent modules installed and conflicts. If someone else has access to the admin section, you may want to see what has been installed recently or what areas have been accessed. Seems that the url got changed somehow. You can also run cron and update manually (cron.php, update.php) and see if that helps.

Anyway, just go to your admin and do what you need from there. Actually, I only use my direct admin link, then I go from that point to where I need to. Just adds one more step, but no big deal.

Try that, then let me know if it works or if you need more help.

Good luck!

Access control page displayed again after increasing memory

drumming_cat commented 26 March 2009 at 23:07

Hi Chris,

Thanks for the tipps. After some extensive debugging I discovered that the page would crash after n calls of drupal_render. It turned out that the number of user roles * number of permissions per installed module could not be displayed due to lack of server memory (local memory_limit was set to 32 MB). Currently, we use 22 roles and have about 80 permissions to administer, so the 22*80 matrix on the access page was too much to handle for the server.

Our server admin increased the PHP memory_limit to 96 MB and I changed the local setting in settings.php entry to:
ini_set('memory_limit', '96M');

It's now running smoothly again, yay :-)
(Let's see for how long once we start adding new roles...)

Cheers,
Tash
