pgadmin4 suddenly not working - ImportError: cannot import name 'view_commit'

[Ni Ne]

pgadmin4 was previously working, logged in this morning and now it's not. Am 
guessing an automatic yum update went through.


I am running CentOS 7, pgadmin4 5.4, Flask 1.1.2


This is the error I am getting in the apache error_log file:

mod_wsgi (pid=14087): Failed to exec Python script file 
'/usr/pgadmin4/web/pgAdmin4.wsgi'.
mod_wsgi (pid=14087): Exception occurred processing WSGI script

Traceback (most recent call last):

    app = create_app()

  File "/usr/pgadmin4/web/pgadmin/browser/__init__.py", line 35, in <module>
    from flask_security.views import _security, view_commit, _ctx
ImportError: cannot import name 'view_commit'

Does anyone have any ideas on how to resolve? Thanks!
