empty content of write page

Hi,
I’m trying to access https://mydomain.com/write url with multiple roles but it always gives me an empty page
I’ve tried with Admin,Author and subscriber roles. in both Author and subscriber roles the writeshare write privilege by default is checked (and not enabled for editing)
I’ve the same issue with https://mydomain.com/profile/Username
only the https://mydomain.com/fanfic works and displays the search form.
Please advise.
