I noticed the site issues banner and not been too upset. But I hadn't noticed this thread before and a lot of it is over my head. Just wanted to add my tuppence worth:
1) An issue I had previously has recurred in the past week. It tells me to log in. As Scotty found before, I was never actually logged out, so I just ignore it.
2) I suspect I am no longer a site sponsor but can't recall any reminders. Would gladly renew. There was a previous issue that when I was a sponsor, my admin privileges disappeared.
3) Further to this, I'm getting ads between posts. There seems to be a suggestion above that this relates to not being a sponsor?
4) Occasional problems posting, as reported above. Page freezes and content is restored on refreshing the page. Sometimes takes several attempts. It actually happened while I was beginning this post. Safari on iMac and also on iPad.
