Hi,
Kindly check which template style it's assigned to that menu item, I guess that template style is using 'feature-intro' layout which doesn't load 'component' block so there is no content show on that page: http://prntscr.com/it2l6b
You can duplicate that template style and assign default layout for it and assign to that menu item.
P/s: I tried to login backend of your site but it seems that the provided login info doesn't work.
Regards
