WordPress and Enigma update, home page sections gone

Hi,

We had a webpage, with very old wordpress and used very old Enigma version.
At first, I updated the wordpress, it was fine, but Enigma theme has problems, the customize page didn worked. Ok, then I refreshed the Enigma theme.
The customize page seems fine now, but every sections disappeared from the home page.
We had theme slider, services block, portfolio block and footer call-out what vanished.
Content rebuilded, and blocks enabled, but its not visible, its also cant see in customize page preview.
I browsed the support topics, tried the tips (for example, back to original versions, switch off is-comapnion, refresh, switch back) but I couldnt fix it.
Could you help..?
