Re: KeyError: 'browser.forgot_password'

Reading the doc of mod_wgsi
(https://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html),
I also added this at the beginning of the pgAdmin4.wsgi file:

python_home = '/usr/local/pgadmin4'

activate_this = python_home + '/bin/activate_this.py'
exec(open(activate_this).read())

And it still doesn't solve the problem ? How is this possible that with
all that, the application seems to not take into account the virtual
environnment ? As I said in an earlier message, the version of flask in
the virtual environment is correct (0.12.4).
I really do not understand at all why it doesn't want to work.

Thanks for your help,

François
