Sorry for the bug I introduced in version 18.104.22.168 and for the delay in uploading the fix.
I did't notice the widget was broken until the following day. Then I release another upgrade with the fix but I forgot to change the Stable tag in the readme.txt so it didn't show up right away. I just uploaded the new readme.txt so you can easily upgrade to version 22.214.171.124.
Please feel free to send me an email or comment on my blog if you find something broken in any of my plugins.
