Call to action default URL

Hi!
I managed to delete the default URL for my call to action button, and now i can’t get it to do anything good. I would be glad if it just took me to the first blog post.
Here’s the website: www.lillblomman.se

Hi,

If you set it back to #primary it will lead to the first post.
It needs to actually target an existing ID. Right now you’ve set it to something non-existent.

Thank you!
