Presentation Archive has been updated to use HTTPS (wikipedia article
), which caused the site to drop offline throughout the day. After many hours I finally narrowed it down to a plugin that was causing an infinite redirect loop. I am confident that all of these issues have now been sorted. If anyone is still experiencing any difficulties please get in touch. If the update is working for you the url of the site should display https://presentationarchive.com/
(with a green some sort of a security lock depending on what browser you are using) instead of http://presentationarchive.com/
(unsecured grey 'i' symbol). I have successfully tested it on Chrome, Safari and Firefox.
