I thought it was a plugin (which it may still be) or the theme but the thing is that the widgets show up on any of the pages or post pages. It is only on the main page that most disappear and I can’t figure out why considering they are all installed correctly under the “widgets” area of WordPress.
A few days ago, my RSS feed coding got screwed up as well (still to be fixed) but the widgets were fine until today. Could they be connected?
