Bug with newer version ?

I don’t know if it’s related to the update of the plugin, but I can’t publish a new article or post anymore. If I try to create a new article, the title is the name of the city of the weather I have configured, it’s saying that it’s published already, and if I try to save, it’s not saving anything, except the title. Also, the permalink is “/wpc-weather/xxx”. If I try to edit an article or a page, I don’t get the content, but an empty field, and the name of my city as the title also !

If I deactivate the plugin, everything is fine again.
