I guess the question is, what if anything do I need to clear out in order to get this to function again? Is there a db entry that I need to delete?
I successfully did this myself if you’re interested. Steps to update yourself:
1) Download the latest version.
2) Extract all the files
3) Replace the wp-content\plugins\teamspeak-3-viewer-plugin-for-wordpress-widget\libraries folder with the new one.
4) Replace the wp-content\plugins\teamspeak-3-viewer-plugin-for-wordpress-widget\images folder with the new one.
5) That’s it. Refresh for success.
