Call to a member function getController() on a non-object

Permalink Browser Info Environment
Hi, I am building a website for a client using your pro blog plugin.
Concrete5 version is Concrete5.7.5.2
Pro blog is pro blog for concrete5.7
The problem is that when I try to add a pro blog list (on home page, it already has blog_section attribute and blog page is removed) I get error

concrete5 pro blog Call to a member function getController() on a non-object
After that I need to get back to previous version of the page to have it running.
How should I fix that? It is a bit urgent.
I have used pro blog for concrete5.6 and I have never had such problems.
Here is my email, if needed:

do you have this issue on sub-pages, or only the home page?
