Steps to reproduce the issue

Upgrade from 3.4.8 (old site long since migrated from J1.5)
Menu items for lists of contacts in category just give blank screen

tried removing SEF URLS to see what URL is being called, and created a new one to compare as I've seen mention of menu issues
OLD URL http:///index.php?option=com_contact&view=category&id=51&Itemid=224&lang=en
NEW URL http:///index.php?option=com_contact&view=categories&id=51&Itemid=460&lang=en

Neither NEW nor OLD menu items work.

Expected result

Should work

Actual result

OLD URL - Totally blank screen
NEW URL - screen with menus, but empty window for contact listing

Also tried rebuilding all menus and menu items, clearing all caches - no effect

NOTE manually removing the &ItemID field from the URL makes the OLD URL work.
However I see an orange "unpublished" flag in the listing.

A totally blank screen (sometimes called a white screen of death) WSOD is a php error message in disguise
Go to the global configuration and set the error reporting to the highest available.
Go back to the problem page and you should now either see an error message on the screen OR in the server error logs

Sometimes, due to a PHP error, a Joomla Extension can stop working and, without displaying an error, lead you to a blank page.

In that case, to find out why, do following:

  1. Check server error logs (not access logs) if you have access to them. (cPanel or other control panels often allow this)
  2. Go to Joomla Administration → Global configuration and enable Error Reporting to Maximum, you can also turn on debugging. – try the action again – if you still get a blank page then goto 3
  3. put the following code at the END of the configuration.php file BEFORE the closing ?>

ini_set( 'display_errors', true );
error_reporting( E_ALL );

4.Check the source of the white page – there might be still some HTML/Errors in the Page Source (Look in your web browser for the “View Source” option)

One of these should give you a nice detailed error message – which you can either email me directly or Google to find a solution

Remember this: A White Page is just an Error Page where the error message has been suppressed by your configuration.

I switched off all caching, switched on debug and highest error reporting
I monitored tail -f on the apache error log, and nothing other than usual mod_security issues, certainly no PHP errors
There's nothing in the Joomla error log other than usual attempted login failures

If I add your lines above to configuration.php, the site gets in a redirection loop and is inaccessible.
When I switch debug on, I see quite a few "NO INDEX KEY COULD BE USED" Mysql errors, unsure if this is significant, but it doesn't look good.
There really is nothing (even viewing source) on the white pages, and no log

Incidentally I can no longer take the site offline as I get redirect loop errors.
All this is very weird as the upgrade produced no errors and I've been using this Joomla installation for years (finally migrated from J1.5 last year)

I'm afraid I had to abandoned 3.5.0 now - reverted to 3.4.8.
Too many weird behavioursa
