Answer 1

Make sure that your website is not compromised. Most likely someone injected suspicious code your website files and due to this, you are seeing the above notice in your log.

Answer 2

This is an issue with a plugin or theme. Try looking for line 18 or 44 in your qa-theme.php.

Or look for a line where you are trying to read the 'title' or 'name' property of an array.

I dont find this error. :(

My site code
http://szh.kz/1.txt    qa-theme.php
http://szh.kz/2.txt    qa-base.php

OK I think it's probably due to a plugin. Try removing each one in turn and see if the errors go away.
