    The previous/next links invoke an ajax call. You get the 500 error from the admin-ajax.php which is the correct receiver for the ajax call.
    This page only checks on the action set in the plugin. I had a quick look into the script. However it is beyond my scope and take to much time to investigate.



    Thanks Jan,

    Yes, I figured as much. It probably is just a small detail somewhere in these 100 lines of code. But being more of a front-end guy I can’t find the error.

    Maybe someone else can have a look at it. Or maybe someone can tell me how much work it would be to fix it, I guess I could pay for an hour or so.

    As far as I see it checks the theme version, pings the API and if there is a newer version it updates the theme. And I have no idea how any of that could break the plugins functionality.

    Thankful for any suggestions.

    //set_site_transient('update_themes', null);

    //If using on child theme be sure to prefix all functions properly to avoid
    //function exists errors
        $theme_data = wp_get_theme(get_option('stylesheet'));
        $theme_version = $theme_data->Version;
