[Plugin: WP-dTree] WordPress database error: [Unknown column 'hash' in 'where clause&

  • I get these messages when I activated the widget in the sidebar. Any ideas? This happened after upgrading to 4.0.

    It seems the old version didn’t drop the table properly. Did you uninstall and delete the old version from the Admin panel?

    Disable WP-dTree 4.0 and re-enable it. It should rebuild the table itself.

    If that doesn’t work, disable and delete (from the Plugins-admin panel). Then re-install from fresh download.

    Let me know how it works out.

    (You can test for this problem by activating a widget (make sure caching is enabled) and update any setting.)

    Hey Ulfben,

    Thanks for the prompt response.

    You were right. I disabled it and then re-enabled it, and the error messages are gone.

    I get the pipe “|” above and lost some styling, but I’ll try to fix that.

    Another question. Since your JS conflicts with another one which i use only on my front page, in previous WP-dTree I deregistered it on the front page in the functions.php.

    However, now that function doesn’t work (see below)

    add_action( ‘wp_print_scripts’, ‘my_deregister_javascript’, 100 );
    function my_deregister_javascript() {
    if ( !is_page() ) {
    wp_deregister_script( ‘prototype’ );
    }
    }

    Any ideas?

    Thanks in advance, and great work on the new version of the plugin ??

    I’m not sure what you’re asking. That function should work. But WP-dTree does not use prototype. If you have animations on it will use jQuery.

    As for styling, read the FAQ first.

    Ok, perfect. Disabling the animations did the trick.
    I will, thanks.

    i got the same error after updating. but reenabling fixed my previous issues too.

    I’ve improved the installation procedure for WP-dTree 4.1, hopefully these un-initiated tables wont be an issue anymore. Thanks for reporting!
