SSL & HTTS not working in my website

I setup an account with Cloudfare and update name server made these changes to support SSL and HTTPS on my website (http://techboxstudio.com/) i am using infinityfree hosting and word press and install (Really Simple SSL) this plugin However, it has been one days since I made the updates and the site is still not showing as being secure with HTTPS.

You dont seem to have a proper certificate on your server. Make sure your server is properly configured for HTTPS and the issue should fix itself.

how can configured for HTTPS pls help me

You best contact your host for that. They need to make sure your server has a valid certificate for your domain.

i am using free hosting infintyfree.net

According to their site they seem to offer SSL on all plans. You best contact them.
