I am unable to edit the sharepoint site in sharepoint designer even though i am site collection administrator on my system.
It prompts me with a message "You do not have permission to do this operations. Ask your website administartor to change your permission and try again or login with user account that has this permission. To logon with different user account click OK."
But if i try to edit on different system its allowing me to edit. I am not getting any clue for this behaviour.
