vB4 Recent Article widget stopped appearing on home page, & not functioning on other page
 

On my home page of www.bigbookstepstudy.com I have had the Recent Articles widget located just under the category widget since I installed Vb 4.0. Yesterday and today it stopped appearing there all of a sudden? I checked the style sheet and it shows its installed properly. Its actually showing up properly on other pages, its just missing from the home page.

Additionally, it stopped detecting new articles. I created two new articles and niether have been picked up by the widget.

Has this problem been posted about previously? Thanks in advance for any guidance.
