Product Page in Backend Not showing After Installing SSL

[wendy1]

I installed Lets Encrypt a free ssl certificate on my site yesterday. Now in the backend I cannot access my products page. There is no error message the page is just blank. Everything else works fine.  Any help would be appreciated.
