As per the FAQ you linked:
1 - Check server error logs (not access logs) if you have access to them.
I've checked this, and there is nothing in the logs associated with CB or any user registration or profile editing.
2 - Go to your Joomla Administration panel, Site --> Global Configuration --> System Tab and turn on Site Debugging, then try reloading page, and check page source (HTML source). Don't forget to turn site debug off again after you have finished.
Tried this. As per my previous post, the page is completely blank. View Source on the page shows one line of code, and it's blank.
3 - If it the blank page is outside CB (no "option=com_comprofiler" in URL), e.g. in joomla during installation, add following to the index.php (or index2.php, whichever is in the URL) in frontend or backend where it gives you a blank page, just after the first " ini_set( 'display_errors', true ); error_reporting( E_ALL );
I go to the Admin panel, and then go to "Components > Community Builder > User Manager". I try to click on a user name to edit it. The URL associated with the link to edit the user name is:
www.seventhkingdomige.com/nj/administrator/index.php?option=com_comprofiler&task=showusers#edit
In fact the link never changes for each user. There is no User ID or anything. I click any user, and it redirects to
www.seventhkingdomige.com/nj/administrator/index.php
If I go "Site > User Manager", the list of users have links that include an @cid[]=xxx
4 - Check your web server error log for errors generated by your website. You might be able to locate the culprit by identifying the logged error.
No errors here...
5 - Often, it's due to lack of memory, see other relevant links below.
I've upped it to 128MB, and even 256MB. Still white screen...
