DavecUK It should be fixed now, the problem has gone away for me.
Seems to be. Sort-of.
It’s some hours after you posted that, and the message about verifying flashed up very quickly and briefy, then disappeared and I was in to the forum. So far, everything seems to be working and, but for that quick flash of a message, I wouldn’t have noticed any change, if indeed it’s still in place. It certainly isn’t (so far) causing me any issues.
It rather reminds me of the dangers of making pretty much any change to a live system, which is that it often brings out the little quirks that didn’t show up in testing, almost regardless of how much testing you do. However, often, it’s pretty quick to tweak and tune a few things, and end up working as it was supposed to. At least, so far.
