here is something that might help:
still no good result sir,,
do you have step procedure how to update owncloud from 10.0.2 to 10.0.6 properly?
I would try commenting out the owerwrite cli url line and try to access the server again, it's blue for some reason.
also try via http oder ip
I can provide you with a scritpt that uses the tar balls for upgrading owncloud form 10.0.2 to 10.0.6
Try to delete the http:// or https:// in the trusted domain array and just leave the domain name for exampel "Example.com"
save, restart apache and try again.
