Enabled the WP lets encrypt plugin in wp but broke site

I installed the wp plugin for lets encrypt and then activated it, generated the ssl and then tried to view my website and got an error saying the site is unencrypted.

I have removed the plugin from the plugins folder but still get the same error, can anyone help. I need to get back to my wp-admin and plugins folder.

My isp has to install the ssl for me…

Regards,

Richard.
