 Note sure what component to set this ticket to, but here is the issue.

 I have a domain with SSL enabled. I wanted to install WordPress in a
 subdirectory (folder) while the root of my website is static HTML pages.
 Installed it, but noticed that the site urls in General settings do not
 inherit https; they are http only. Change them to https and click save and
 then I get too_many_redirects error and locked out of admin. Have to go in
 db to change back to http or do a complete reinstall of WP.

 Turns out this is related to "mixed content". I reinstalled WP and before
 changing http to https, I noticed the source code had shown http (for
 assets) and https as well mixed in. Reset General settings to https and
 again, error and locked out.

 Finally came across a few plugins for this issue: SSL Insecure Content
 Fixer and also Really Simple SSL. I tried the first one and it worked,
 although I still had to manually change the General site url settings to
 https. Everything worked.

 I then disabled the plugin, manually changed the site url to https again,
 and was locked out again. Reinstalled WP but this time tried the other
 plugin (which automatically changed the site url setting to
 https....everything working as well.

 So it appears this has been a long-time issue when looking in Google and
 knowing there are plugins to fix this, means that it's a problem that has
 been around for a long time with the core and installation of WP in a sub
 folder on an SSL enabled domain. Technically, people should not require
 the use of a plugin to solve this.
