How to create a “random” link?

Hi there!

I’m using the Spacious Theme and it suits all my needs.

I have one question though: I need to show posts ramdomly. I’m going to have a link named “Random” on my page and I need that every time someone clicks on it a different post is shown. I tried some different tricks, but they still didn’t work out.

I asked them on their support forum, but they said they couldn’t help.

Could anyone here please help me?

Thanks a lot!
