Last blog post link directs to homepage

Hello,

I’m having a strange issue on the blog page. When clicking the link to the last blog post it directs me to the homepage of the website.
Editting it in the backend and clicking the preview button generates a 404 page not found error. The 1st blog post is working fine.

What I tried:
– Saved permalinks, changed it to default and changed it back to postname, didn’t help.
– Deactivated all plugins, didn’t help.
– Changed back to default WP theme, this solved the problem. (so it’s something in Enfold)

Running WP4.0 and Enfold version 3.01

Cheers,
Jaap
