Title: 4.7.X and java Last modified: January 29, 2017 --- # 4.7.X and java * [frankasw](https://wordpress.org/support/users/frankasw/) * (@frankasw) * [9 years, 3 months ago](https://wordpress.org/support/topic/4-7-x-and-java/) * Hello! * something is wrong with the connection to a lot of java scripts after update to 4.7. I got about 14 errors with thinks like tinymce and the admin-bar not working (not even to talk about visual composer and some theme). Mainly it affects the frontend so I wait for an update to solve the problem (Or I could downgrade the system…) * But maybe there is a simple solution? If you know, pls. share, I would be very thankful … * > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) > [http://velovilnius.lt/wp-includes/css/admin-bar.min.css?ver=4.7.2](http://velovilnius.lt/wp-includes/css/admin-bar.min.css?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) jquery-migrate-3.0.0.min.js:2 JQMIGRATE: Migrate is installed, > version 3.0.0 [http://velovilnius.lt/wp-includes/js/admin-bar.min.js?ver=4.7.2](http://velovilnius.lt/wp-includes/js/admin-bar.min.js?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/wp-embed.min.js?ver=4.7.2](http://velovilnius.lt/wp-includes/js/wp-embed.min.js?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/underscore.min.js?ver=1.8.3](http://velovilnius.lt/wp-includes/js/underscore.min.js?ver=1.8.3) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/backbone.min.js?ver=1.2.3](http://velovilnius.lt/wp-includes/js/backbone.min.js?ver=1.2.3) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/wp-emoji-release.min.js?ver=4.7.2](http://velovilnius.lt/wp-includes/js/wp-emoji-release.min.js?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/admin-bar.min.js?ver=4.7.2](http://velovilnius.lt/wp-includes/js/admin-bar.min.js?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/wp-embed.min.js?ver=4.7.2](http://velovilnius.lt/wp-includes/js/wp-embed.min.js?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/underscore.min.js?ver=1.8.3](http://velovilnius.lt/wp-includes/js/underscore.min.js?ver=1.8.3) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/js/backbone.min.js?ver=1.2.3](http://velovilnius.lt/wp-includes/js/backbone.min.js?ver=1.2.3) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) notes-common-v2.js:32 Uncaught ReferenceError: Backbone is not > defined at notes-common-v2.js:32 at notes-common-v2.js:158 admin-bar-v2.js: > 2 Uncaught ReferenceError: _ is not defined at admin-bar-v2.js:2 [http://velovilnius.lt/wp-includes/css/admin-bar.min.css?ver=4.7.2](http://velovilnius.lt/wp-includes/css/admin-bar.min.css?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) [http://velovilnius.lt/wp-includes/css/dashicons.min.css?ver=4.7.2](http://velovilnius.lt/wp-includes/css/dashicons.min.css?ver=4.7.2) > Failed to load resource: the server responded with a status of 500 (Internal > Server Error) Viewing 1 replies (of 1 total) * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [9 years, 3 months ago](https://wordpress.org/support/topic/4-7-x-and-java/#post-8713563) * Internal server errors (error 500) are often caused by plugin or theme function conflicts, so if you have access to your admin panel, try deactivating all plugins. If you don’t have access to your admin panel, try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)( no Dashboard access required). 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. If you don’t have access to your admin panel, access your server via [SFTP or FTP](https://codex.wordpress.org/FTP_Clients), or a file manager in your hosting account’s control panel, navigate to /wp-content/ themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue. * If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your SFTP or FTP client to view invisible files. * If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’ll need a more detailed error message. Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that specific time period. If you don’t have access to your server error log, ask your hosting provider to look for you.
