I was admonished in another thread not to make dupe threads but this is different than the 404 error Repeat:: -This has nothing to do with 404 errors:
Last night the following happened to me
I wanted to add an rss feed for Good Morning Silicon Valley and one for the Phila. Inquirer Health/Science feed
That action made my sidebar disappear and a few sidebar widgets moved down to the bottom. I thought it might be the Capital letters I was using to name the RSS feed but no such luck...
Tonight the same thing has happened and I got the sidebar back by taking out both rss feeds widgets.
Dr. Mike told me to add them back so that they could see the problem so I have added 1 rss feed and the sidebar has
disappeared/partially (some items)moved to bottom of page
