Support » Plugin: Simple Staff List » Having trouble getting it to work

  • Sorry, I’m not hugely technical, in fact not at all really. I was pleased with myself for installing your plugin into my wordpress site, but I can’t get it to work. This error comes up:

    Fatal error: Call to undefined function get_the_post_thumbnail() in /home/medavia/public_html/wp-content/plugins/simple-staff-list/_inc/admin-views.php on line 78

    I’m sure I just need a step-by-step guide to getting this working.

    Thanks very much.

    Hi Jack,

    That is actually an error that comes up because your theme (probably an older one) does not support post thumbnails. I’ll be pushing an update for the plugin this weekend that will prevent that error from popping up but you still won’t be able to add a staff photo.

    You can add the following line anywhere in your theme’s functions.php file:

    add_theme_support( 'post-thumbnails' );

    After you add that line, it should work. Let me know if you have trouble.

    You can read more about post-thumbnails here.

    Thanks Brett

    I learned the hard way not to meddle with the functions.php file, but I’ll send the code to our I.T. chap.

    You’re very kind.
