Magento 2.1.3 static css files not generating

Question

When I open the front end of my website it can't find different files and they are only css files not being found e.g. /pub/static/version1486733880/frontend/Meigee/blacknwhite/en_IE/css/styles.css

I have cleared all the caches and ran php bin/magento setup:static-content:deploy, but it didn't make a different. It was okay until this morning, but then it stopped loading. If I change to the luma theme then everything will load fine. I have removed the folders in this thread, but it didn't make any difference. The owner of the folders are all the same and the permissions are set to 755. What am I doing wrong?

EDIT: Here is the content of the pub/static htaccess file.

<IfModule mod_php5.c>
php_flag engine 0
</IfModule>

<IfModule mod_php7.c>
php_flag engine 0
</IfModule>

# To avoid situation when web server automatically adds extension to path
Options -MultiViews

<IfModule mod_rewrite.c>
    RewriteEngine On

    # 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>
