Post and Page Excerpt Widgets is a nice plugin to show post/page excerpt as as widget in sidebar position. You can download it from wp code from here. One I thing I noticed about this plugin is it has a common bug that I faced many times while using query_posts. When I use this query_posts it’s break some conditional loop like is_home(), is_category() etc but there is another function get_posts in wordpress that does the same thing but don’t have similar problem. Once I discussed about this problem in one of my old posts. Please check that posts for better sense from here is_home-is_single-is_category-is-not-working-in-wp!.
Let me focus to this writing again 😀
As Post and Page Excerpt Widgets is using the query_posts function for custom query it make’s problem for conditional tags. Let me show u solution and it’s like my that posts.
In you theme functions.php add a new function if not exists yet
