Blog Help....

The Blog has not allowed me to add the gadget "Recent Comments" which lets us all follow what others are contributing.  There are some other issues.  Everytime I make a new post.... a pink strip shows up with a yellow caution sign saying "An error occurred while trying to save or publish your post.  Please try again."  It stays on and occasional disappears.....    These all started when I believe Blogger made blogspot.ca different from blogspot.com.  I will try in the next couple of weeks to get some help.  I secured the domain thehappytrappers on WWW for Canada.  I might be trying to move the Blog over to that domain.... I will look into it.  "Recent Comments" are important.  Art... George sent his deepest sympathies.
