[TYPO3-english] t3blog: content elements not visible in BE

[Wenzel Dirk]

Hi 

When I create or edit a blog post and add content to it none of the content appears in the backend form. 
When I look at my blog sysfolder in list view, the content elements are there, but they seem not to be connected to a blog post.

In FE the blog post are shown but not the content.
(I have a page with FE-Plugin and a sys folder where I put post and content - but the same happens when using a standard page)

What can I do?

t3blog v.1.1.1
t3 v. 4.5

Many thanks 
Dirk
