Hey Amin, thanks for the amazing theme!
I am having issues with the anchor menu.
I set it up exactly like you explained in your tutorial but although it does scroll correctly on my page text starts disappearing, some sections won't link (my STILLS section) and it sometimes gets stuck.
I deactivated all plugins and it's still not working properly. I have a feeling it has something to do with the Laytheme Carousel I am using for the full screen stills section. Can that be a factor somehow?
I am using Firefox to edit but I have the same issue on Chrome. I cleared caches several times on my browsers and on the Wordpress site using W3 total cache.
