I just installed Knowners, and had it working fine. Now, suddenly, while the image can be dragged, clicking on the tags does nothing.
I am not sure what has changed. I have tried deleting and reinstalling the plugin, as well as manually recopying the original files in.
The only thing I might have done is open the "Edit Links" dashboard, though I did not submit anything through it - is it possible that that has corrupted a file somewhere that I can't see? Something outside of the plugin folder?
