here is my setup:
siteurl (wp): wp.website.com
when i am in the admin with this plugin enabled and only the following options checked:
-Always use HTTPS while in the admin panel. This setting is identical to FORCE_SSL_ADMIN.
-Any page that is not secured via Force SSL or URL Filters will be redirected to HTTP.
and wp-config does NOT contain a force ssl admin directive
clicking the preview button on any post that is still a draft (post id =2 for example), i get redirected to https://www.website.com/?p=2&preview=true
which gives me page does not exist error
changing the URL manually in the browser to https://wp.website.com/?p=2&preview=true
displays the preview just fine.
for some reason your plugin is rewriting the preview URLs
disabling the plugin fixes the issue. but that is not an option for us so please help!
