I've an interesting problem again. In the backend, when I select "show all blog entries" or "show all pages", I get an white page. Site bar and menu bar are there.
Via the calendar I can access the single entries or call a page and click on edit.
WP 4.4.1 OSX 10.11.2 running MAMP
Just in case I have granted you access. The site url is http://www.4d-consulting.com
