Campaign wizard goes to blank screen at "Target Lists" Step (v7.6.4)

[kyriakoy]

Apply to versions 7.6.3 and 7.6.4.
When I open the new Campaign wizard, If I click on Target List or Campaign Header, the screen goes blank.

Hi @kyriakoy What browser are you currently using? Can you try and refreshing your browser's cache?

Hi,

Yes I have multiple times with diffrent computers, connections, browsers etc....

I found that the problem is only with an existing Campaign (created with prior versions). When I refresh the page I show to log the following:

Wed Jun 8 17:22:10 2016 [1027][1][DEBUG] SugarBean.load_relationships, Error Loading relationship (created_by_link)

then I search for :

grep -rl "assigned_user_link" ./ |grep "Prospect"

./cache/modules/Prospects/Prospectvardefs.php
./cache/modules/ProspectLists/ProspectListvardefs.php

As you can see exist only at cache. Is this proper ?
I have already Rebuild Cache and Relatiotionships

Permissions are:
sudo chmod -R 775 cache custom modules themes data upload config_override.php

Thank you,

I check it also and with another existing Campaign with the same problem (blank problem) and in sugarcrm.log I didn't found the previews error
But one additional debuging with Firebug shows Internal Error 500 and apache log shows:
