Static Content is not loading after upgrade

The main issue was caused by the incorrect rewrites work ( as @Marius told ). There was no RewriteBase in my directory pub/static/ and Apache could not find the files because searched for them from the root folder. After we’ve added: RewriteBase /pub/static everything start working.

How it worked:

by this address:

http://m2.uchuhlebov.web.ra/pub/static/version1481885888/frontend/Magento/luma/en_US/mage/requirejs/mixins.js

the rewrite should work:

RewriteRule ^version.+?/(.+)$ $1 [L]

as the line started from the root folder:

/pub/static/version...

it hasn’t worked and could not redirect to the file, needed.

Rewrite without base:

Rewrite with base:

Here a part of my .htaccess file from the pub/static (rewrites) :

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteBase /pub/static
    # Remove signature of the static files that is used to overcome the browser cache
    RewriteRule ^version.+?/(.+)$ $1 [L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-l

    RewriteRule .* ../static.php?resource=$0 [L]
</IfModule>

How to disable static-files versioning:

If you do not want to use static files versioning you can disable this feature in the Magento admin area:

It is possible to change this setting for default scope using the following MySQL query:

INSERT INTO `core_config_data`(`path`, `value`) VALUES ('dev/static/sign', 0) ON DUPLICATE KEY UPDATE `value`=0

Then execute next command to clear a configuration cache:

bin/magento cache:clean config

PS: My answer is actual for the apache2 users. If you are using NGINX see this answer (by @kevin-javitz)

If you are running Nginx, here is the fix. You probably have your own conf file, you need to update the /static/ part with this, they have updated part of it specifically: # Remove signature of the static files that is used to overcome the browser cache section:

location /static/ {
    # Uncomment the following line in production mode
    # expires max;

    # Remove signature of the static files that is used to overcome the browser cache
    location ~ ^/static/version {
        rewrite ^/static/(version\d*/)?(.*)$ /static/$2 last;
    }

    location ~* \.(ico|jpg|jpeg|png|gif|svg|js|css|swf|eot|ttf|otf|woff|woff2)$ {
        add_header Cache-Control "public";
        add_header X-Frame-Options "SAMEORIGIN";
        expires +1y;

        if (!-f $request_filename) {
            rewrite ^/static/(version\d*/)?(.*)$ /static.php?resource=$2 last;
        }
    }
    location ~* \.(zip|gz|gzip|bz2|csv|xml)$ {
        add_header Cache-Control "no-store";
        add_header X-Frame-Options "SAMEORIGIN";
        expires    off;

        if (!-f $request_filename) {
           rewrite ^/static/(version\d*/)?(.*)$ /static.php?resource=$2 last;
        }
    }
    if (!-f $request_filename) {
        rewrite ^/static/(version\d*/)?(.*)$ /static.php?resource=$2 last;
    }
    add_header X-Frame-Options "SAMEORIGIN";
}

Go to the database and insert a row in core_config_data table:

INSERT INTO core_config_data (scope, scope_id, path, value) VALUES ('default', 0, 'dev/static/sign', '0');
