A GoDaddy security check showed problems (yellow triangle with an exclamation point inside) for both of these:
Heartbeat Extension - Enabled
Strict-Transport-Security - Disabled
However I couldn't find any reference on how to correct the problems.
Solved! Go to Solution.
In my case I solved it with a .htaccess file on my root folder. Add the following line to the file:
Header set Strict-Transport-Security "max-age=31536000" env=HTTPS
I hope it helps you.
