Can I rename a portal while in trial ?

Can I rename a portal while in trial ?

Hi there,

I've just started a trial of Zoho, I'm driving crazy trying to change the name of a portal. I created one (I don't even know what is a portal) and as the system didn't let me use the name I wanted I typed xxxxxxxxxxxxxxxxx and the portal was created under that name. Now I want to change the name but I can't find the way. I already googled it and the solutions found don't work.

any help?

Thanks!
