Problem with sort by...

Nothing was happened...

Yes, VM is updated to last version 2.0.22c.

Nothing was happened... Still these same errors...

Yes, VM is updated to last version 2.0.22c.

Do this, go to templates\hot_ecommerce\html\com_virtuemart\

rename folders:

categories
category

temporally to:

_categories
_category

layout will be broken because that will disable template layouts and vm default will be active, but you will be able to test is that happens.

After that return original folder names

Errors was identical, like before...

Interesting is this same result after change template to Beez5...

But, when I am making installation directly from actual J! and VM (without "hot_ecommerce25_hotstart.zip" step)sorting is working without problems...

Yes that then tells us problem is strictly something with virtue-mart so better ask their support.
