I just installed the back-end and the front-end on my Linux server (Ubuntu 18.04). But, on the login page, when I attempted to register a new account, a red empty box appeared under the form buttons (and stays there ahah), and nothing else happened. How to know if the back-end is correctly installed? Maybe there are some prerequisites missing…? Is there someone who could help me out with this please?
Thanks a lot in advance!
