Problem solved! It was my mistake. I had wrong page number on Widget Logic function on my child theme. Strangely there was also second login widget on footer widget area and I didn’t notice it. After fixing these issues the problem was gone. Thanks for your help!
Hello
I have only added style.css file with comment section and functions.php file with my_theme_enqueue_styles() function as it is advised in Codex (https://codex.wordpress.org/Child_Themes). My website is not yet public, because I’m doing it for my customer and I don’t want to publish it before it is ready.
I had to create child theme for Twenty Sixteen. After that, bbPress sidebar went on bottom of the page. What I have to do to get sidebar back to side of the page?
Thanks for help. Problem got solved with Widget logic.
