I installed the new version of iRedmail 1.4 on Debian 10.4, during the installation I only noticed an error message that the "webpy module not found", but despite it completed the installation as expected, then I restart the server and while booting it gave an error with iRedadmin When I tried the administration page http://hostname/iredadmin it does not respond, showing
Internal Server Error
when I look in the log files it gives an error that says:
iredadmin.py ", line 9, in <module>
    from libs import iredbase
there is no web module.
I noticed inside /opt/..../lib/iredbase.py
has a line   import web
Can somebody help me please?
