Hello,
Shop page is at place http://prntscr.com/uqi7ja But you added the duplicated page with shop title to your menu and it was the problem because that page was just simple empty page. So, check it now.
I don’t see problem with the fonts. Could you, please, provide us with links to pages where you have the font issue and also screenshots of the problem. You can use the Lightshot screenshot tool to share the screenshot.
Regards
