Hey again.
Thanks for replying.
Firstly, the coding of the site has nothing to do with me unfortunately, I'm just an unpaid skivvy, sorry mod <img src="https://www.ubbcentral.com/boards/images/graemlins/wink.gif" alt="" /> . Sometimes the site appears as a .cgi URL and others as a .php - not sure of the difference myself!
I had a search around, once I'd posted and found another message similar to what you posted there Graeme regarding security settings, so I got the member to check her security settings and cookie settings.
She was set to Medium for Cookies, so I got her to change it "Accept All" (which is how mine is set) and it seems to have worked.
Thanks for all your help <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
