Cannot post in my Website after Norton Update

I have a secure website and now I can not post on it.  This was not an issue prior to the last major Norton face change.  How do I get rid of this problem?  It needs fixed and I am not a good computer person.  This last Norton update and facelift is costing me.

My web site comes up under the administrative section  but when I go onto the pages there is nothing at all showing.  This means I can not change my webesite.
