In the end all text widgets that have error messages should be removed.

If you are having issues where things are not showing up on your sidebar this may help remedy that situation. You don't have to change them all. Just the one's that have the error message.

Hope this helps those with issues of not seeing ads or other things embedded into your sidebar.

I noticed the error messages when I was integrating my Amazon CPM Ads onto my WordPress site which is another training that I am working on and plan to release shortly.
