Can you share the shortcode you’re using to exclude posts? It should be similar to:
[a-z-listing display="posts" post-type="page" exclude-posts="5,6,7"]
Versions 2.0.5 and 2.0.6 didn’t include any changes to the code that excludes posts, so I’m not sure why it would stop working for you….
This is the shortcode that I am using:
[a-z-listing display="posts" post-type="page" exclude-posts="2832,1021,3112,322,2498,3238,2500,304,2891,3176,713,3203,1980,1989,1986,1999,1977,1983,1993,1996"]
I’m betting this is because you’re displaying pages in the list. The plugin is using a different function to pull pages, currently, which is incompatible with the exclusion parameters. The good news is I’m working on reducing the usage of that other function to allow for more consistent behaviour in circumstances such as your example above. The bad news is it’s not ready yet 🙁
