I get the redirect error with the two most recent versions of WordPress HTTPS. However, after rolling back to 3.0.1 it resolved the problem.
However, this version caused a massive drop in my Google ranking as it stopped Googlebot from being able to crawl my whole page as it said 'cookies' were mandatory (I am assuming Googlebot crawls with cookies disabled).
In short, I cannot use 3.0.3, 3.0.2 and 3.0.1. I believe the plugin to be a great plugin, it is just causing me problems lately.
To everyone out there, WordPress HTTPS is the best HTTPS plugin for WordPress, i've never had issues in the past, just on this occasion.
@Mvied - do you have a patch for version 3.0.1 that makes my site content crawlable by the cookies disabled Googlebot?
Hope you can help.
