I saw your blog post about the deprecation of offline_access and how we'd need to generate a new access token every 60 days, but I'm being repeatedly, every few page refreshes in the WP dashboard, told I need to generate a new token.
Your Facebook Access Token for WPBook Lite has expired. Please visit the settings page for WPBook Lite and grant a new access token. Until you do so, cross-posting to Facebook and import of comments will fail.
I generate the new token, and everything seems to go successfully, but a few minutes later I'll get the message to generate a new token again.
Also, no posts are being published since the most WPBookLite update.
