Hey Matrixter, I had this same issue. I was able to include the fix in the shortcode using this [catlist id=153 numberposts=-1] The -1 is show all posts. Just put a number in its place for how ever else you may want to show.
So 10 posts would look like [catlist id=153 numberposts=10]
Hope this helps you out!
Hi Matrixter,
I think this is the same as the bug I’ve reported to the forum, see
https://wordpress.org/support/topic/bug-in-settingslist-category-posts-v051?replies=1
That is, assuming you are using a fairly recent version of List Category Posts (files have been renames in this and an incorrect edit was made to a filename that’s embedded in the code).
The only fix I know of at the moment is to make the correction as shown in the link above.
Hopefully the author will put it right in the next release!
Hope this helps.
