Created 1st wp site but used upper and lower case letters

I created my first WordPress site tonight and it works fine here…

But not here

https://www.fareways.ca/mvcater/

I tried renaming the directory in file manager of my web host, but then neither address worked.

Can anyone tell me how I can get it to work with lower case letters?

I learned many a lesson tonight including not to use upper and lower case letters in the wordpress installs… ??
