    A really great background image plugin. But I get this error.

    context: trying to import images in with NextGen uploader. selecting to only show background images for home page.

    Here’s my php error trace.

    to reproduce the error:

    assumptions: only select home page to display background
    you have to be logged in as admin.
    go to any page other than ‘home’ to see the error.

    Thank you for providing the error trace, which helped me locate the cause.

    There might be a contributing factor of the theme you are using, however I have modified the affected code to use a different approach for what it is supposed to do.

    I will release an update this weekend, which also includes a few more other improvements and new goodies. If you don’t wish to wait until then, you can temporarily disable the cause by editing the file wp-content/plugins/background-manager/app/Myatu/WordPress/BackgroundManager/Main.php and comment line 561:

    add_action('admin_bar_menu', array($this, 'onAdminBarMenu'), 90);

    Thanks again!

    Just to let you know that I’ve released version 1.0.6, which addresses the problem you were experiencing.

    Let me know if this solves your issue, or if it persists.

    thanks for the quick fix. unfortunately, I switched to the ‘better background’ plugin, and did a hack, so it would only display the background slideshow for the front page–it was the only functionality I needed. So I’m unable to give more feedback at this time.

    I prefer your plugin, but I’ve already coded everything up, and the site works. Client is satisfied, so I’m not gonna switch plugins. I will most definitely you background manager for my next project, since it provides greater flexibility, and options than ‘better backgrounds’
