After I edited an existing node, I got this error message:
Notice: Undefined index: nid in views_handler_field_node_page_title->render_link() (regel 68 van ***/sites/all/modules/page_title/views_handler_field_node_page_title.inc).

Unfortunately it results in a WSOD.
If I deactivate Views 3, the error is gone.
Can anyone help?
