@patrykos360 please read the instructions carefully 😀

RE header-buddypress.php you must post the code I gave at the BOTTOM, below all other code. What you did is paste the code at the TOP of file which is a no-no

RE sidebar-buddypress.php the second code must be posted at the BOTTOM, below ALL OTHER code. What I see is that you placed it before the closing !– end sidebarSubnav and !– end sidebar which is incorrect.
