Hi Oliver, You were right. The problem was in Cookies and Content Security Policy plugin. I just needed to allow for this link to be seen on site. Thank You for helping.
Now everything is working great on desktop, but on mobile version my theme isnt working properly. When I go to a page, my header (where the logo is) expands and navigation menu isnt where it is supposed to be. Then I hit refresh button and everything comes back to normal. This happens on every page on the site. Try it.
Do You have any idea how to fix this problem?
