Some time ago I released the WordPress MochiAds plugin beta, and after some time, it stopped working.
The problem was the feed included two new fields,
recommendation, that made the plugin not compatible with the feed.
You can download the fixed version at this link.
Then, no matter if you already have the plugin installed or not, follow the instructions as it was the first time you install it.
You won’t lose your previously installed games, and you will be able to add new ones.
In a few days I’ll release the final version of the theme too.
