You could say it was maintenance but more me trying to find out the problem and causing other issues. I think the main problem is with the SSL certificate(s), there seem to be different ones for www. and mail. and that's causing browsers to say "watch out, there's a problem as they don't match. Don't go further as there be dragons". Or similar. We moved the site to a new server a few months ago and I'm guessing that's when the issue started. I, and quite a few of us, rely on the browser history (mine autocompletes to www.eastdulwichforum.co.uk/forum/list.php?5) which works fine but some people go to www.eastdulwichforum.co.uk which is broken. And some go the long way round to Google to look up the forum and then click the link, which is currently showing mail.eastdulwichforum.co.uk, which is also broken. I have some server people looking at the issue so hopefully it'll be fixed soon, thank you for flagging it up as I would never have known about it.
