For some reason my Magento shop always redirect to https. I set config -> web -> unsecure -> base url to http://, so that can not be the problem. Changed also store view to check all views.
And htaccess is also not redirecting to https.
But I do not know where in my code the site is redirecting to https. I already changed to the default Magento theme, but still the website is redirecting to https.
Maybe I edit a core file a time ago, but I do not know what file it can be.
Is there a way to find the location of this problem?
