This error was generated because your PHP version is still in 5.2.0.

As per WordPress Requirements you need to have PHP version 5.6 or greater.

The Heartbeat API allows your browser to communicate with the server using AJAX calls when you are logged in to the Admin page. This allows other authors to show that a post is being edited and for the plugin developers to show real-time notifications.

Since this will slow down your server if you have too many requests you need to control it by installing “Heartbeat Control Plugin“. This will control your Heartbeat Locations and override Heartbeat frequency.

Hope this helps!

The Jetpack plugin is causing this error. To access your website again you need to access your files via FTP client and rename the folder Jetpack to disable it.

The file should be located under HRB/hrb/wp-content/plugins/jetpack

If you have access to the file system, you can edit the wp-config.php file and enable debugging to get an insight of what is happening.

Can you name what plugins you have installed in your site?

Great! You’re welcome.

Go to your Appearance > Editor > style.css and find this:

.main-navigation {
clear: none;
float: left;
width: 55%;
}

Change the width to 100%.
