Cannot redeclare class wp_facebookapiexception

    I occasionally receive the following error:

    Fatal error: Cannot redeclare class wp_facebookapiexception in /home/www/lmc-tv/devlmc-tv/wp-content/plugins/all-in-one-event-calendar/lib/facebook-php-sdk/base_facebook.php on line 25

    I suspect that this plugin may be conflicting with Facebook Feed Grabber, but this plugin seems to protect its declarations. The error seems to happen intermittently which has made debugging a real pain. Has anyone else run into this? I’m running version 1.10.9-standard.

    Thanks,
    Louis

  • Hi,

    I am also getting a facebook error when I try to install. I have not gotten this to install yet due to the errors. I’m running the Pro edition, 1.11.4-pro.

    I’m running Custom Facebook Feed Pro and have disabled it to try installation, but that didn’t stop the error.

    WordPress database error: [Duplicate key name ‘subscribers’]
    ALTER TABLE wp_ai1ec_facebook_users ADD KEY subscribers (type(2),subscribed)
    Warning: Failed to upgrade Facebook DB schema in /var/www/***/***/wp-content/plugins/all-in-one-event-calendar/lib/plugin/Ai1ecFacebookConnectorPlugin.php on line 353

    I’m also getting this error:
    Plug-in disabled due to unrecoverable database update error

    Database update has failed. Please make sure, that database user, defined in wp-config.php has permissions, to make changes (ALTER TABLE) to the database.

    Why would I get an error like this when all the wp-config.php settings are correct? I’m able to add content to WP.

    Hope you sort your issue and this helps!

    Best,
    Tiff

    Solved my issue. It was due to APC caching being enabled on the server with too small a memory limit. This led to some of the objects being discarded partially through page loads.

    trenee71, I think your symptoms are a result of a different issue, and I suggest creating a new topic.

    Thanks,

    Thanks for the tip, @superlou. I had a similar problem on one of our client sites
