Thanks for your help..I explain you the situation:I have create My portal and I have create a site,I have uploaded documents,images,I have added users to site,I have managed the alerts..so,I'm studying Sharepoint features..I want create My Site but if I click on My Site link I receive this message:"The security validation for this page has timed out. Click Back in your Web browser, refresh the page, and try your operation again."
This occurs when I enter with administrator account..I've create another user with member rights and when I try to create My Site I have another situation:the portal tries to create the site but it fails..
What do you think?
I hope I've explained well my problems..
