Feels a little weird speaking with myself, anyway, by playing around I got 95% resolved:
just changed:
[...]
} else if(is_feed()){[...]
to
[...]
} else if(is_feed() || is_search() || is_single || is_archive){
[...]
Which seems to exclude it from search, archive & single. However, I’m still struggeling with “posts_nav_link” to not point to any sideblog entries…working on it. ANY hints appreciated.
