Can you help?


Hi Donna,

Is this still an issue for you? Perhaps it was temporary? If it is has anything changed on your HelpSpot server? Any updates to the server itself, etc?


Hi Ian, Sorry for not coming back (I’ve turned into my worst kind of client)
It’s all working fine now, so it must have just been a glitch.
Thanks for checking
