pgAdmin4 - V3 - Problems managing passwords - Mailing list pgadmin-support

Hi

I recently installed v3 of pgAdmin4

When setting up the passwords for each of the databases, I kept getting the
message;

"Object type <class 'str'> cannot be passed to C code"

Although it appeared to save the password

A server reboot later, when I try to to the databases, it prompts for the
password, when I input the password and click the OK button, I get the
response "Internal Server Error - click for details"

Clicking to view the errors shows the following in a message box which
cannot be dismissed

The server encountered an internal error and was unable to complete your
request. Either the server is overloaded or there is an error in the
application.

The platform is Ubuntu v16.10


The log on the server window reported
