By default, once your SSL certificate is installed, visits to the unsecured version ("http://www.tudominio.com") will not be automatically redirected to the secure version ("https://www.tudominio.com").
We will tell you how to configure in WordPress the automatic redirection to "https", or in other words, from port 80 (http) to port 443 (https).
The "Really Simple SSL" plugin allows you to make this configuration extremely easy. You only have to proceed with its installation:
Go to the Wordpress administration panel. Usually, this is found in the "wp-admin" directory, for example:
In the left menu, click on Plugins > Add new and in the search field enter "really simple ssl":
Click on the button Install now of the Really Simple SSL plugin, and once installed, click on the Activate button that appears in the same place.
You have already configured the automatic redirection to "https"!
