Cannot access Admin control panel -

[2ntow]

In the past few weeks something has changed and is impacting my ability to access the Admin control panel.  After entering my login information, it is going to a screen saying 

The information you’re about to submit is not secure.  Because this form is being submitted using a connection that’s not secure, your information will be visible to others. 

When I click on the Send Anyway box, it goes back to the Admin login screen.

The site has never been an https site and access up to a few weeks ago to the control panel was not an issue.  Do I need to upgrade to https to correct this or is there a work around?

You have switched to https using the server, but not actually changed the software to use it. You need to follow the instructions in the following location
