Hello,

Thanks for the details, I can see the error message in the URL you mentioned above.
As you can see the fatal errors are outputted from "elementor" plugin:

Fatal error: Uncaught Error: Call to a member function get_component() on null in ***wp-content/plugins/elementor/modules/page-templates/module.php:345 

Please try these:
1) In case it is a compatibility problem, please deactivate other plugins(Except Toolset plugins), and switch to wordpress default theme 2017, and test again
2) If it is fixed, you can activate other plugins one by one, try to locate the problem plugin/theme.

In other site the same problem with elementor after last update. When Elementor disable, all work. But I need elementor to work.

So it is a conflict problem with Elementor plugin, can you try with a fresh wordpress installation + the latest version of Elementor plugin + Toolset plugins, try to duplicate the same problem.

Then provide detail steps to produce the problem, then we can report to our developers, otherwise it will be considered as an exception

And the PHP errors are from Elementor plugin, you can also check it with Elementor support:
hidden link

I temporarily restored the previous version Elementor.
My issue is resolved now. Thank you!
