What I did was uninstalled this then tried to go into my database & see if there was dups. There wasn't. So I reinstalled it without touching the "fix the tables" file.
Of course uninstalling it deleted all my categories so I had to re-add them. Then I was trying to make it so guests could see because I figured you might show up. But when I saved the guest group permissions there was a database problem. So I had to use the "fix the tables" file after all. Then I was able to save.
I added some more videos & sure enough I screwed up again. Trying to edit an entry doesn't bring back the link to the video so if it is wrong until this is fixed you'll have to delete & start over. Otherwise all other options come back (category, language & link to image). So I switched it from Animals again to Music again. Same problem as last time.
But this time I went over to "rebuild counters" & the 1 under animals disappeared & reappeared under Music like it was supposed to. Rebuild counters fixed it for me.

Thanks for adding that.
Other then being able to edit the video link should it be wrong...I think this is working like it's supposed to. Thanks for creating it.
