Support » Plugin: Instant Articles for WP » Fatal error after Facebook password reset

  • I changed password on Facebook account used to authenticate this plugin against Facebook API. The plugin does not handle this very well. I cannot access the plugin settings and more importantly I cannot access the list of my plugins. Therefore I am unable to manage plugins on my site. Would you be able to look at this? Please see a snippet from error log below. I am going to try to delete the authentication token from database to make it work.

    PHP message: PHP Fatal error:  Uncaught Facebook\Exceptions\FacebookAuthenticationException: Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons. in /var/www/

  • I managed to solve a similar but slightly different issue on my site, maybe this solution will help you too:

    “I’ve managed to solve the issue. Here’s how I did it:

    1. Go into PHPMyAdmin, and pull up the wp_options table
    2. Search for the option name: instant-articles-option-fb-page
    3. Delete the value and save

    Once you’ve cleared this value, the plugin enters its initialized state — which allows you to re-authenticate with Facebook. From there you just walk through the “setup” process, but all your settings and options will still be there.

    NOTE: Definitely back up your wp_options table before doing this, it didn’t wipe my other FBIA option values but YRMV.”
