I cannot edit pages with cornerstone anymore, is it broken? X THEME

Please help me! I was working on this website happyfitplatform.com and it crashed, I got error 500, then my hosting provider said it is usually caused by themes and plugins. Now it is running again but I cannot edit the content with cornerstone anymore, I do not get the elements, inspector etc window. What can I do? It is very urgent! Thank you
