I just changed over my sites to https and noticed that most pages are showing as having non-secure contents with that popup in older IE versions that so many still use. Here is one such page: https://www.mu-43.com/threads/79927/page-2 Unless I'm mistaken, the only non-secure content on that page is one of the attachments which was created before the switch to https. The URL for that attachment is http://www.mu-43.com/media/19766/full ... which gets automatically rewritten to https://www.mu-43.com/media/19766/full ... but still trips the browser warning. My sites are photography forums, and I noticed that the vast majority of pages give this warning. Is there an easy solution for this?
