I wasn't installing anything new. I just updated plugins and theme. Only modification which I lastly added, was custom css from you to delete counter in scroller, but it was working fine.
Ok, so after that submenu openers it is working, but now there are these "arrows". Before there were no arrows, but it worked in the same way. I think this is the last time, that I am updating this theme. It makes a lot mess.
Yes, it is here: http://sztukaportretu.pl/test/
Also i updated today theme and Dark overrite header stopped working. I seleceted dark theme for blog part (which has white background) and i still have there white header.
And that parralax? If I try put it into site with shortcodes, it isnt in full screen mode. So i set album as main page instead, but that's not optimal.
I think now it is harder than it was before. Maybe its bugged after upgrades. You go into appearance -> Photoproof import -> Design Importer.
But better do copy of your site before. Today i kinda f***** up my site by doing that. :P
