blank white screen help

Hello, could somebody help me?

My website link is http://twinmesinhoreca.com
the website is showing blank page, just white page.
Tried renaming the plugin folder to plugin_old and deleting the cache from firefox and log in to Wp-admin, not showing and then tried wp-login.php, also not showing>

The only thing I did yesterday before it crashed change the ht access page to redirect the naked domain and w3total cache and disable cloudflare.

thank you for the help
