Magento2 not auto generate static files

Question

i've some issues with auto generating static files in pub/static folder

after use magento setup:static-content:deploy if i delete some static file generated by deploy like css and i point to the url like:

<my_domain>/pub/static/frontend/<my_module>/<my_theme>/en_US/css/theme.css

magento2 not auto generated it anymore... i need some tips!

• i'm in developer mode
• i've clear var/cache and var/view_preprocessed folders
• i've flushed magento2 cache
• i've set Server side less compilation
• if i use magento setup:static-content:deploy all works perfectly!

• Krishna ijjada: you need to run magento setup:static-content:deploy to generate deleted file. as you said it works fine , the file will not generate automatically unless you run deploy command.
• Claudiu Creanga: this is not a real question. why should you expect something to work if you delete files?
• itorso: cause some days ago it works, to recompile less for example i delete file in pub/static/[***]/css and var/view_preprocessed and refresh the page

I've resolve this issues, for my mistake i've delete the .htaccess from pub\static

<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ドル [L]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-l
 RewriteRule .* ../static.php?resource=0ドル [L]
