I am using the "Sidebar Widgets" plugin and it works great. Except, I attempted to use the RSS option to display an RSS feed in the sidebar. What happens next is curious:
I drag the RSS feed to the appropriate sidebar, click on the button to open the options and enter the RSS feed URL and select how many posts I want to display. After closing that window, I click on "Save Changes" and it disappears. In fact, if I have 5 RSS widgets selected, they too disappear from the display area below. I have to change that number to something else, hit save, and then they re-appear. Then I try the whole process again and they disappear again.
So I can't display any feeds. I do not have this problem with the Text plugins. Only the RSS plugins in "Sidebar Widgets".
Any ideas? Thanks!
