Error Code 108 Invalid frob

I'm trying to link to my Flickr account, but receive the message shown above.
It could be because my Flickr email address is different from that used for Directory Opus, but I don't know how to correct this.
Any suggestions?
Thanks in advance
Steve

Make sure you're on the latest version (12.7) as Flickr changed their authentication mechanism and earlier versions of Opus can no longer authenticate successfully.

I upgraded yesterday then tried to add sync with Flickr, which I hadn’t noticed before.
