Can't click on main buttons

I have indstalled the theme, and changes the image and other stuff.
When I added links to the two buttons on the main page, I can’t get them to “click” to another page.

I can see that the URL is fine, but when I press the buttons nothing happens.
the page is www.jbks.dk

Hope it makes sense

I am having the same problem www.entresuccessproject.com. HELP! Thanks.

Redownload the theme and reinstall please: https://athemes.com/?wpdmdl=15202

Do I need to back up files? Will I lose all of the work that I have put into building the site already?

Ok, did it and it worked beautifully. I didn’t lose any of my work! Thanks again Vlad!

Thank you @Vlad!
