I'm really surprised to see the [resolved] tag in front of the title. It's not resolved, I believe.
You said to check in the Custom Meta. But where? I checked sql, but didn't find anything! Can you please let me know where I can find that? And can you please tell me if I can get the previous views back?
I used to use "Top 10" plugin and the theme had it's default view counter. I used to use both of them and they worked perfectly. But another admin deactivedated the "Top 10" plugin and installed your plugin. And the view is gone (view used to be shown by the theme).
Now again I deleted your plugin and re activated the "Top 10" and it shows the views of top 10, not the view used to be shown by the theme by default. :(
Had more than 11000 views on posts, and now they have 0 view. After visitnig several pages again I tried installing your plugin, it rests all the view of the default, not the "Top 10" views.
