I don’t have that plugin installed.
I’d like to be sure I’m understanding this entirely. I understand that I do need to go through all of the database & files, but…
If, in WP settings AND in the database the site url and home are configured properly with https, AND and the post urlS, but other links within the site have not yet been fixed (even if it’s only a couple of links), then when the site is loaded in a browser, posts and pages will NOT automatically go to https, but rather go to http?
In SOME browsers, all pages go to http. Loaded in firefox, the homepage goes to https, but if typed in manually, other pages do NOT go to https (menu links on the site go to https just fine).
I’ve tried the methods in the link supplied in esmi’s post above:
edit wp-config.php
edit theme’s functions.php
relocation method
Just seems odd that if post, home & site URLs in the database have https, some browsers don’t follow this…
