Hi,

I recently started using Drupal and am a newbie here. In general Drupal has all necessities I need for my website. :)

Especially defining roles is a very good feature. There are 2 pre-defined roles "Authenticated" and "Anonymous". I added a new one and went into "Access Control" and 3 columns of roles listed just fine. However when I add one more role, the access control page goes blank and NOTHING is displayed. If the last role is deleted, then the access control page is displayed fine again.

Has anybody experienced this kind of problem (or similar) and knows how to troubleshoot?

Thanks very much.

The odd thing with me is that I created a whole bunch of roles, and things worked fine for a while. Then this morning I started getting the blank page. I found this post with a Google search, removed the extra roles I'd created and now things work again.

I've eliminated the possibility of this being theme-related. I was orginally using my own theme, but switched to Zen and still got the same problem.

Because all I get is a blank page, I'm really not sure how to investigate this problem further. It's a bit worrying though. I'd really appreciate any de-bugging tips so I can get more information about what's going wrong...

I'm experiencing this as well after an upgrade form 4.7 to 5.2! Can anyone help!?

Me, I seemed to find the page at another url: admin/access/permissions. Damn, it disappeared again!!?

blank page errors are apache errors, have you checked your apache logs ? are you getting an error listed there about exhausted memory ?

typically a blank page is caused by not enough memory alloted to your installation, this happens often on default installs of PHP, or on shared hosting.

investigate the handbooks area, specially Troubleshooting FAQ's. Search for the link for exhausted memory and begin to see if you can tweak the amount of memory alotted to you to avoid blank pages.

Thank you!

I allocated more memory in settings.php using the command:

ini_set('memory_limit', '24M');

and now it works.

*phew* - I thought I was going out of my mind...

Would allocating more memory increase performance of the site? And what is the recommended max? Hope this is related to this post. If not please let me know and I will start a new post. Thanks

Your need of memory depends heavily on your modules used. If you use imagecache the use of 96M is recommended. Also Panels and Views are hungry for M if I recall correctly. I have set mine to 96M and I think that should do for the most part.
