Why did the MODX site stop working?

Question

MODX

The problem arose on the resource dka34.ru
I must say right away that when I log in as an admin, the site works perfectly.
When just a visitor, the main page is just blank. Moreover, there are no calls to any snippets on it, etc. The worst thing on it is the slider, but it has nothing to do with modx.
Then, if you go to other pages, they open normally ( dka34.ru/uslugi for example). The only thing is that on the page where Gallery is called ( dka34.ru/gallery), there is no gallery, although when I log in as an admin, everything is there.
Recently the site moved from another hosting, but everything worked perfectly. And I didn’t update or change anything, I just go to the site and it doesn’t open. The hosting says that everything is ok with them, nothing has changed.
There is nothing in the logs on the hosting, nothing in the logs of the modx itself. I turned on the display of errors in .htaccess, nothing too. I don't understand how to deal with this, can you please point me in the right direction.

Answer 1

To get started:
1. Try to make a test template or an existing Minimal Template and assign it to the main page of the site.
2. Also check the id of the resource in the settings, which should be shown as the main one.
