403 - 'you are forbidden' error

I've been getting oodles of 403 errors telling me 'Forbidden You don't have permission to access /(whatever the name of the page is) on this server. 

It's making the morning spam hunt a bit difficult, and it took me a fair few goes to post this up.  Is it the server or buggy software? 

As an admin, that will be caused by another admin getting to the problem post before you and deleting it. 

Or are you experiencing it in other ways?

Well it seemed to happen for around half an hour this morning (around the time I started this thread) and I think I got about 30 errors altogether for all kinds of pages, not just spam-deleting.  They weren't anything like the usual screens I get if someone has deleted a spam before me - they were completely white backgrounds, not 'permies' style ones.  I'd never seen them before, and they seem to have gone away now, so maybe it was the server playing up. 

If they turn up again I'll see if I can get a screen-shot.  I did wonder that maybe if other members had seen these, they might assume they'd been banned and get upset.

I just got this. I'm using a friend's computer, so I had a moment of terror that my various nefarious internet activities had somehow got me 'forbidden'
But then I could access from a different angle, so clearly just some error. Whew!
