Completely perfect, it was everything I wanted a long time! Could determine a featured picture (miniature) for all my posts in each category with a single click! Loved, congratulations to the developers.
The mine also had this error, but I found the settings for the plugin, an option that solved my problem … you must click the link where it says: “Requesting access to private albums” … then appears “Checking user: ok “and the albums will work again as before!
