Thanks for the reply,
I did correct the login issue by restoring from a recent backup. There is a lesson in there somewhere 🙂
As for the initial reason for my problem—
My wordpress installation was not initially set up in the root folder on my server and I had changed hosts recently so I had to monkey around a bit but eventually found some solutions here at https://codex.wordpress.org/Moving_Wordpress. The solution for my issue was corrected by following the Moving Directories on Your Existing Server section which is about a 1/3 of the way down the page.
Hope this helps someone else.
