Support » Fixing WordPress » Sidebar and Widget's are gone!!

  • VictorZanta


    Hey guys a few days a few days ago i decided to update all of the plugins on my website. After i did this i found that my side bar on my website had vanished. Also the widget area although there is not responding and i also see this error

    Fatal error: Call to undefined function dynamic_sidebar() in /home/viczan1/ on line 80

    I have tried to uninstall and deactivate all the plugins and still nothing. When i changed theme also the same problem occurred there which is really weird so its obviously something very deep in the coding.

    Any help would be great.

    I had the same problem and posted it here. I didn’t get any replies, but reinstalled WP and they reappeared. WP has been doing all sorts of weird things over the past few days. I have about six colleagues who have been suffering a plethora of different issues.

    The upgaradation of plugins somehow changed the widgets.php in wp-includes/ (Codex). Can you replace the widget.php from a fresh copy of WordPress? Don’t forget to take a backup of your widgets.php. If anything goes wrong, then you can retrieve what it was.

    Just make a try. I don’t know whether it’s the solution or not.

    Hi Victor and Verbandverse,

    dynamic_sidebar () has been core code in WP for quite a while.

    Unless you running WordPress < version 2.2, I would recommend you do a reinstall of the base software,

    go to wp-admin/update-core.php and click the “Re-Install Now” button and follow the prompts.




    Exactly the same thing has happened to me too – been googling and ended up here. My site has been working fine for months, updated plugins and now get an error message on my WIDGETS settings page –

    Fatal error: Call to undefined function dynamic_sidebar() in /home/... /wordpress/wp-admin/includes/widgets.php on line 80

    widgets.php @ line 80 = dynamic_sidebar( $sidebar );

    I wonder if it’s a single plugin that’s causing this, or a specific combination of 2 or more ? I use *lots* of plugins, but if someone wants to help pinpoint this then please list yours here, then I will cross-check to see if we share any.

    I’m guessing it’s not so common, otherwise the boards would be full of HELP posts !



    @everyone (except the OP) – if you need help, you need to start your own threads. It does not work to have multiple people in the same thread and it’s unlikely that your issues are identical even if they may, on the surface, appear to be.
