Help with WebUI for SeaFile on TrueNas Scale Cobia

[EnigmaNas]

I have installed SeaFile on TrueNas Scale using the APP installation within TrueNas, and everything appears to have installed correctly, as the app shows as running, but I cannot access the webUI. When attempting to do so, I am presented the login screen where I enter the email address and pwd for the user account I supplied to the install. This login does not work, because I get “Forbidden (403) - CSRF verification failed. Request aborted.”
There appears to be some permission problems with the install fresh out of the box!
Does anyone know how to fix this issue? I should probably mention that I am a serious noob, and that any replies should NOT assume that I have prior knowledge of anything
Thanks in advance for any assistance.
