Can you try making a full refresh of your browser and try logging in again? It's possible that sometimes some scripts fail to load on the viewing browser which why incidents such as a login page doing nothing after pressing the submit happens.
If the form still acts nothing after that, please try clearing your browser's cache and try again. And if the problem persists after this, please let us know.
