Problems

Anyone else having this issue with WordPress? since I purchased my domain name through WordPress while writhing a post I am unable to Preview the post when I click on Preview I get a page that says” Not Found!, what you were looking for doen’t exist or isn’t here anymore. We are sorry:( Please return to the home page or use the search box above”

anyone else get this or is it just me am I doing something wrong or have I not done something right?

Thank you
