Question for moderators

[albee1952]

Several times now(over several weeks), I cannot post a reply in some threads(I get a white screen saying "Access Denied; you do not have permission...".

The weird thing is that I always use the same browser(and have for years) and it seems totally random(it even happens in threads where I have already posted before). Today, it happened again so I opened the DUC with Microsoft Edge(instead of the usual Chrome browser) and got the exact same message for the same thread. Minutes later, I posted a reply(with screen shots) in another thread without any issue.

If anyone has any insight into how/why this happens, I'm all ears
