Hi @K4-713, @vshchepakina and @violetto

I have tried to track login action, it submits user name and password to https://wikimedia.myshopify.com/account/login and then redirects me to store.wikimedia.org/account without https.

When I manually access https://store.wikimedia.org/account, it redirects me to login page. That means, the cookies generated by last login action has no effect... I have not idea about this...

I also tried to force login action to submit my username and password to https://store.wikimedia.org/account/login, I am also redirected to store.wikimedia.org/account. This time, however, when I manually access https://store.wikimedia.org/account I can stay on my account page and retrieve my information, the cookies work!

So my thought is

1. Change the login action from https://wikimedia.myshopify.com/account/login to https://store.wikimedia.org/account/login, to get cookies work for https.
2. Then we can add a setting to redirect users to a page with https.

However, I didn't find the a place to set up the login action in theme files.

Any suggestions please?

@K4-713 do you have any suggestions?

@K4-713 @vshchepakina
I have updated login page liquid and added a JS snippet to force all access to be redirected to https.
However, this is not the best solution, it may affect SEO of the website.
Please figure out a way to achieve this request on the server side.
