** You may notice some changes here... **

iPad had logged me out as of this morning but at least allowed me to log in on the Communities page, which Chrome on Windows 10 won’t do for some reason - have to open main CIPD website which says I’m logged into them already - despite Communities saying otherwise . But logging out of it and logging back in again then going back to Communities page seems to fix the Communities login.

(Swathes of spam appeared overnight too.)

I've sorted the spam... and will speak to colleagues on Monday.

There is some info on the login workaround here, David - although we should have this fixed early this week.

I hope so. I'm also having to log in through the main site as the Community page refuses to log me in (using "Edge"), simply going back to the home page, and if I visit the site more than once having opened from the main site it seems I am no longer a "Champion" as the link vanishes. To re-set I have to re-start my computer and log in again, as even closing the browser and reopening doesn't work. 

There's not much point doing anything else, as I do not want to open my 'mail to another tsunami of unwanted "subscription" notifications, so have everything but this thread turned off as I was getting nothing from any other thread I had actually contributed to.

Hi Peter - I'll be sharing an update with the community shortly as we have fixed most of these issues. Might be best if I called you, so I'll sort something out today.

That sounds like the same problem I've been having. It seems to be fixed as of this morning.
