site working slow

Choose a Back-up Plugin.
Install it through the Plugins > Add New.
Activate it and go to its settings (there should be a link) and configure it.
Run the back-up.

I used Fetch, I have Mac, a MacBook Pro and an iMac late 2013 with Yosemite – work wirelessly with Vodafone ultrafast fiber.
It worked fine until a month ago, since then watching video is very slow despite the wireless networking features to over 250 Mb / s – I’m trying to optimize my site, first I would like to backup (which I had not activated at ‘beginning with Bluehost) and I downloaded the plugin WordPress Backup that I can not turn on because it asks me PHP> = 5.3.0 version required. – I downloaded PHP 5.3.3 but do not know how to install it

There are numerous vulnerabilities with PHP version 5.2. Ask your host to upgrade PHP to a supported version, or move hosts.

What about PHP 7.0 version? – How can I install it?

@fcrosti…
Your host is Bluehost: https://whois.domaintools.com/fcrosti.com
Read this: https://my.bluehost.com/cgi/help/447

When I test your site, everything work fine. Your site work fast. I just need 2-4 seconds for open your site.

Note: If you are using the share hosting (Bluehost Share hosting). Sometime you will got the slow connection.

Good luck!

I know that but are videos running veri slow – Thank
