Can’t edit pages

So WordPress was working perfectly untill I deavtivated and reactivated the plug-in called Youzer. Now my pages weren’t showing anymore, only the header. After I deactivated all my plug-ins and turned them on one-for-one it seemed that if I deactivate the plug-ing Essential grid my content would show again.

However, I still cant edit my pages weirdly enough. See screenshot: https://snag.gy/deMPZG.jpg

I really don’t know how I can fix this problem and hope someone can help me.
