After installing your plugin on WP 3.6.1 I got it to work as far that I can insert the shortcode and a list of post-titles ware shown.
[multisite_posts blog_id=1 post_no=10 excerpt=true thumbnail=true]
Unfortunately I get an error message when going to the Deatil page:
"This is somewhat embarrassing, isn’t it?
It seems we can’t find what you’re looking for. Perhaps searching can help."
Antoher thing does not work. I cannot deactivate the thumbmail and the excerpt with this:
[multisite_posts blog_id=1 post_no=10 excerpt=false thumbnail=false]
Any idea what to do?
