CSS is not loaded on mobile devices

After investigation and talking with some sysadmin friends, it happened that there was a .htaccess with rewrite rules for mobile devices in the root of WordPress, in wp-content and in all folders in themes and plugins.

I removed all the .htaccess, refresh the root .htaccess with only wordpress needed stuff and everything is good now.

I really think it was a security issue with W3 Total Cache, however, I won’t try to reproduce it.
