Double slash in error message.

I’m migrating my site to a new server and its not nearly as easy as it should be for me.
Right now I’m receiving an error message. I’m seeing 2 forward slashes in the address which I think is the problem.
jvond.com//wp-includes/load.php (https://jvond.com/index.php)
Any ideas how to fix this?
Thanks! ~J
