Http to https: weird display

I installed a Wordpress site from scratsh.
I nstalled Cwicly, theme, plugins, etc.
I began to work on the Front Page template.
Then, I installed a SSL Certificate: Let’s Encrypt™ SSL

http: everything runs well, backend and frontend.
https: the backend runs well but the frontend is weird.

I regenerated HTML, CSS and cleared caches of browsers (Edge, Chrome) but the display remains weird.

I created a new page to display with Index template and the display is weird too.

Herewith a couple of screenshot.

Hello @weedor,

Could you possibly check your WordPress Address (URL) and Site Address (URL) fields in SettingsGeneral
They should normally include the HTTPS protocol which seems to be the problem here.

Great @Louis
Thank you, all is all right now!
