PROBLEM Wordpress site broken with Javascript errors with zero plugins or themes installed. The issue followed different devices, OS’es and different browsers. SOLUTION User account corrupted. The wp_usermeta locale field had an invalid value of “regular”, and nulling the field solved the issue. DETAILS JS console shows this:

The key is to send a response header like this: Access-Control-Allow-Origin: * In the Apache web server, one enables this via the following directive: Header set Access-Control-Allow-Origin * This requires the use of mod_headers, which is enabled by default in Apache. For example:
LoadModule headers_module modules / mod_headers . so
. . .
< VirtualHost * : 80 >
ServerName www . your . domain
ServerAlias * your . domain
DocumentRoot / var / www / yourdomain
DirectoryIndex index . php index . html
Header set Access - Control - Allow - Origin *
< / VirtualHost >

Edit the wp-config.php file in the root of your WordPress Install. Search for this line: require_once(ABSPATH . ‘wp-settings.php’); Just before it add this line: define(‘CONCATENATE_SCRIPTS’, false ); Save, exit and refresh the page in your browser. It would also be a good idea to empty your browser cache. Original Post: http://www.carnfieldwebdesign.co.uk/blog/wordpress-fix-add-media-button-not-working/
