Seafile website messed up

I don’t know why, try to do fresh-install already more than 3 times but result always showing seafile mess-up website after login (please see attached screen-short)
downloaded installation file from Releases · haiwen/seafile-rpi · GitHub
can anybody help me what’s wrong?

Here is a guide that I have written, if you following this from point to point you will have a working seafile server, I’m just telling you this because it seem that you need to read up a little how it works and then after that ask the questions.

I think something wrong with latest seafile v.6.2.3
I install seafile v.6.1.2 then everything OK
After that I upgrade to seafile v.6.2.3 everything still OK

6.2.3 works as intended nothing wrong with it.
