I am installing my first version of DNN.  I am unable to add a table or a picture to a page.  It says to contact the administrator.  I get this when I am logged in a host, administrator or the user that I set up.  What security switch have I forgotten to flip?  I want to be able to put a picture or table on my module. 

Thanks for taking time to responde.  I am using 4.8.0.  My web hosting company told me that they had to turn off the security guard on my domain.  That resolved my problem.
