Blogs won't open (no rights?)

Hi,

I'm installing EasyBlog on my site. A lot works fine, but now I discovered an issue with not-showing my blogs.
As you can see at my site (https://www.onthaasten-en-genieten.nl/blogs) it is not possible to op the blogs. When I click on 'read more' I get the message 'U bent niet bevoegd deze pagina te bekijken.' (In English 'you don't have the rights to view this page'.

I believe it has to do with EasyBlog, but I am not sure.
Can you help me?

Thanks, Meindert
