Title: Java Script Errors with WP 4.4.2 Last modified: August 31, 2016 --- # Java Script Errors with WP 4.4.2 * Resolved [Unity2014](https://wordpress.org/support/users/unity2014/) * (@unity2014) * [10 years, 3 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/) * My blog post editor is not working like it’s supposed to so I added the SCRIPT_DEBUG to the wp-config file. It did not work. In fact it seemed to make it even worse. I am using Chrome, but I tried another browser and it has the same errors. I ran a an error report on Chrome and got 83 different java script errors. The URL I was at when I did the error report was: [http://unityofboulder.com/wp-admin/post.php?post=5467&action=edit](http://unityofboulder.com/wp-admin/post.php?post=5467&action=edit). Here is a screen shot of some of the errors: [http://content.screencast.com/users/folkmaiden/folders/Jing/media/aca2a6c3-0c7e-49f0-b440-2a331478416b/2016-02-16_1450.png](http://content.screencast.com/users/folkmaiden/folders/Jing/media/aca2a6c3-0c7e-49f0-b440-2a331478416b/2016-02-16_1450.png) Viewing 14 replies - 1 through 14 (of 14 total) * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [10 years, 3 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/#post-7072925) * Try [downloading WordPress](https://wordpress.org/download/) again, access your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients), or a file manager in your hosting account’s control panel, and delete then replace your copies of everything on the server **except** the `wp-config.php` file and the`/ wp-content/` directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. * Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them. * Thread Starter [Unity2014](https://wordpress.org/support/users/unity2014/) * (@unity2014) * [10 years, 3 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/#post-7073027) * I replaced all of the WordPress files, minus the wp-config.php file and wp-content folder, and it did get rid of some of the Java Script errors. * However, the editor still looks weird for pages and posts. See screenshot: * [http://content.screencast.com/users/folkmaiden/folders/Jing/media/a51f0330-5b11-4a58-831b-c12256691f95/2016-02-17_1509.png](http://content.screencast.com/users/folkmaiden/folders/Jing/media/a51f0330-5b11-4a58-831b-c12256691f95/2016-02-17_1509.png) * And, when I “visit page” while logged in, the black editing menu at the top is no longer there. Instead, there is a navigation pane at the bottom of the website below the footer with links to the various dashboard items. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [10 years, 3 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/#post-7073028) * Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause. * If that does not resolve the issue, try switching to the Twenty Sixteen theme to rule-out a theme-specific issue (theme functions can interfere like plugins). * Thread Starter [Unity2014](https://wordpress.org/support/users/unity2014/) * (@unity2014) * [10 years, 2 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/#post-7073165) * I tried deactivating the plugins and widgets and that did not help. I also switched the the twenty sixteen theme, but got the same javascript errors. I tried overwriting the wp-includes file, that didn’t work either. * Thread Starter [Unity2014](https://wordpress.org/support/users/unity2014/) * (@unity2014) * [10 years, 2 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/#post-7073166) * javascript errors are also preventing the slider images from loading on the homepage as well… * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [10 years, 2 months ago](https://wordpress.org/support/topic/java-script-errors-with-wp-442/#post-7073167) * That’s very odd. I wonder if a browser extension, or issue in the browser, is causing the JavaScript to fail. * First, please make sure that your browser is up to date by visiting [https://whatbrowser.org/](https://whatbrowser.org/) * If it is not, please try updating your browser or switching to a different browser. * If it is, please do these two things: * 1. Try clearing your browser’s cache and cookies. * 2.

It worked! All the issues are fixed.
