I just started to notice that the website keeps dropping out of HTTPS mode and going back to normal after a few page views, and then i have to go back and type it in for it to go back into HTTPS otherwise after a few page views it goes back again. I have my homepage set to the HTTPS version so i can go back using the home button but just a few pages into the forum and its gone again.
Using Chrome Version 30.0.1599.14 dev-m
After a quick test, it looks like it is HTTPS everywhere except when i have loaded a topic to view the responses.
I have also Tested this in IE11 (only other browser I have installed) with the same results.
