I've been wondering for a few months now why searching for new posts showed 0 results about 80% of the time, when there were infact new posts. Clearing cache each time fixed it but I think I finally worked it out.
The page at 'https://forums.nzgames.com/search.php?searchid=1450' was loaded over HTTPS, but requested an insecure image 'http://forums.nzgames.com/cron.php?&rand=123'. This content should also be served over HTTPS
If I open that image, search works. Any chance of fixing the HTTPS for that please?
