After installing Moodle for the first time, I get the following error on the first page after installation (which is my User account):
Exception - Argument 1 passed to file_get_all_files_in_draftarea() must be of the type integer, null given, called in [dirroot]/lib/form/filemanager.php on line 336
Also, did something go wrong in the installation? It looks very different from what I expected. I thought Moodle would look more like Totara (I only have experience with Totara). Please see the attached screenshot. The main page looks more like a "User Dashboard" than an actual LMS. I'm a bit confused. It feels like something was not installed.
