Recently installed Passbolt to a Ubuntu 20.04 VM, when ever I access the administration page I am presented with a blank page. It takes me to /app/administration/email-notification then does nothing. I can see periodic “GET /auth/is-authenticated.json” events in the access log even though it’s a blank page, the error log doesn’t display a line for “closed keepalive connection” but does for every other page I navigate to. Please help.
