If you're running two clients on the same PC, have you got them configured with different display settings profiles with different local webserver ports? If not, they'll be conflicting and you will that these issues.
Also, I notice on your screenshot that XMR isn't configured correctly. If you're not running XMR, then you should leave the settings for that empty rather than filling in wrong values.
If you are running XMR, then you need to correct the XMR public address as it appears wrong, or the Player can't connect to it, so check XMR is running, and any firewalls etc aren't blocking the connection.
