Title: Fatal Error – WP_Widget not found Last modified: August 31, 2016 --- # Fatal Error – WP_Widget not found * [krakenexe](https://wordpress.org/support/users/krakenexe/) * (@krakenexe) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/) * I’m trying to manage a site for a company I started working for last week, we run a lot of wordpress installations off a single server. We’re currently experiencing an issue where we get `Fatal error: Class 'WP_Widget' not found in /home/intaglio/ public_html/wp-includes/widgets/class-wp-widget-pages.php on line 17` Thrown at us on ever single page. I tried manually updating by deleting and adding the newest version of wp-admin, and wp-includes, and updating the contents without erasing the folder in wp-content. I’ve tried disabling all of the plugins by renaming the plugins folder plugins.hold, and I’ve even tried renaming the themes that were currently active, with no affect on anything. * I’m at the end of my witts here, and appreciate any and all help you guys are able to provie, I’m quite a wordpress nooby but I feel like the steps I took should have fixed it. * For other documentations we have a second developer who is somewhat lazy and doesn’t keep backups so restoring backups is a no go, and I called the hosting company and they have no backups. I haven’t been able to reach out to him however, so there has been no help due to management. Also to note you can’t access the wp-admin page. * Here’s the website for those of you out there that feel that you need the live example [ltyc.org](http://www.ltyc.org) Viewing 8 replies - 1 through 8 (of 8 total) * [David Artiss](https://wordpress.org/support/users/dartiss/) * (@dartiss) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411352) * Which version of WordPress is installed? This sounds like an installation issue and simply re-installing a fresh copy of WordPress (don’t touch the database – it’s just the files!) should resolve this. * Thread Starter [krakenexe](https://wordpress.org/support/users/krakenexe/) * (@krakenexe) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411367) * I’m running version 4.3.4, and how do you mean it sounds like I need to re-install a fresh copy of wordpress? I’m really nooby, so I presumed that updating those folders with the latest version might have fixed it. * [David Artiss](https://wordpress.org/support/users/dartiss/) * (@dartiss) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411369) * What about the files in the root folder (the folder that contains wp-includes, etc)? From past experience, it’s more than likely going to be a file there. So, basically do the same but the files there. * Thread Starter [krakenexe](https://wordpress.org/support/users/krakenexe/) * (@krakenexe) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411456) * I’m not sure but I managed to find a wpress file… So I restored from that. But I lost a ton of content, I did however make a back up. * [David Artiss](https://wordpress.org/support/users/dartiss/) * (@dartiss) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411488) * Ok, I think you really need to get a professional involved. There should be no reason to be losing content if you’re replacing the root WP files, so I suspect you’ve managed to do something else. * Thread Starter [krakenexe](https://wordpress.org/support/users/krakenexe/) * (@krakenexe) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411517) * I restored from a .wpress file and ended up losing some of the site. I’m supposed to be a somewhat professional here, but I’m not too positive on all of wordpresses nuances and how it works completely, but I was hired in to be a wordpress developer though… The other developer here knows even less and only edits themes and sends them live. * Thread Starter [krakenexe](https://wordpress.org/support/users/krakenexe/) * (@krakenexe) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411518) * Plus I wasn’t the one who built this site… So I’m confused on a lot of stuff, especially since it wasn’t maintained. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [10 years ago](https://wordpress.org/support/topic/fatal-error-wp_widget-not-found/#post-7411520) * Try re-uploading all files & folders – **except** the wp-content folder and wp- config.php & root .htaccess files – from a **fresh** download of [WordPress 4.5.1](https://wordpress.org/download/release-archive/). Make sure that you delete the old copies of files & folder before uploading the new ones.
