bug in widget options

Hello,

I’m using your plugin since a long time on my site https://www.buzzwebzine.fr/ and it was working well.

But I just notice a bug in the widget admin :
I can’t change this 2 options :
– configuration of the publication : no option is checked by default, I would like to display an image but when I check the option it’s not applied after saving
– statistics parameters : only “number of views” is ckecked by default and I can’t change it

All the other options of the widget admin are working well.

I don’t know exactly since wen it’s not working. I just tried to change the option and now I can’t choose what I want. I had an image before and now I can’t ??

I have the last version of wordpress 4.7.3, maybe the plugin is not working with that version ?

Thanks for your help.

Erwan
