I just insalled version 1.8.2 of the plugin on my website, example here:
I can see that it works by default but the settings page in the control panel seems not to react to any change I'm making, it's not saving my settings and it keeps remaining as default.
For example, I'm trying to use the medium stars and set 10 stars in advances settings.
Screenshot attached below for how it looks in the admin control panel:
You can see that the live preview and the theme is stuck on loading, I suppose it's not a problem that is related to other plugins.
Your assistance please, I don't mind giving my wordpress details if necessary via my e-mail.
