Problem with capabilities for comments

I installed this plugin and it’s generally useful. However, I noticed that the last comments in the widget on the home page are missing. More specifically, they are visible to administrators, but for others logged or non-logged users they aren’t visible. I did a little test and noted that function get_comments() returns an empty array, and it returns right results to administrators.

All comments are approved and visible to all throughout the site. I suppose there is some problem with permissions and get_comments(), but I’m not sure. I didn’t see any settings for visibility of the comments and that function.

Does anyone have a solution for this situation?
Thanks in advance!
