I just did a fresh install and am definitely having the same issue. the configs seem fine.
[
localhost] -> works.
[
localhost] -> doesn't work.
"Not Found
The requested URL /mysql was not found on this server."
... ah ha!
I tried [
localhost] and clicked on: MYSQL MANAGER -> works.
It turns out the URL needs to be:
[
localhost]
Good luck,
