Can't get into Dashboard since installing SSL and Redirecting

Permalink
I just recently installed SSL and have been working through issues/problems getting it to work. I am now able to login to my website but when I click on the Dashboard button is gives me the 'This page isn't redirecting properly' and doesn't display the dashboard. The address in url showshttp://www.my website name/dashboard/
Why is it not finding the dashboard?
How do I get it to find dashboard?
Where is the dashboard located?
What code can I change to get it to find the dashboard?
I am a novice.
