I followed the suggestions of the topic you redirected me, but the problem still persist.
Joomla use default template style when u edit the template from fontend view, At present you are using a home layout for your menu item home as default template on your site does not have component blocks in the Layout so u are getting this error .
So your Default english template style ( for example ) should have the component block inside like the default template has.
I tested it on your site switching layouts and this solved the issue.
