There is a workaround that was posted by Zack Katz:
Go to Wunderground.com
In the “Search Locations” box, type in your location
Click on the location when it appears in the auto-complete box
When the page loads, copy the URL. It will likely look like this:http://www.wunderground.com/q/zmw:00000.4.17340
Copy the part of the URL after the /q/. In this example, it would bezmw:00000.4.17340
Use that as your location in the shortcode, like this: [wunderground location=”zmw:00000.4.17340″ /]
That should work!
For Depoe Bay OR, the code is: zmw:97341.1.9999
Version 2 did away with the Settings Page, below is an exerpt from the Wunderground Plugin Page:
“Version 2.0 got rid of the default settings page; now shortcodes and widgets are configured individually”
Just updated to the latest version of the plug in and the issue still occurs.
Is there any place I should be looking to stop the duplicates?
