After I update Cornerstone from v5.0.1.1 to v5.1.1 I loose my whole Portfolio feature from Wordpress and subsequently all portfolios throughout my site. When I restore (long live Updraft :-)) to before the Cornerstone update my Portfolio are back again and working.
Of course this may be caused by a plugin conflict, but how to find this and resolve it. I cannot be stuck with the v5.0.1.1 Cornerstone forever.
Your assistance & support is greatly appreciated.
