    • Article Type: General
    • Product: Aleph
    • Product Version: 19.01

    Problem Symptoms:
    * After installing aleph21 and running 20 -> 21 Upgrade Express, OPAC doesn't function.
    * Apache is running and showing the proper URL, with no errors in the www_server_4521.log or the apache error log, but trying to connect to the OPAC gives a 503 error:
    "The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later."

    Cause:
    The port for the aleph module in ./alephe/apache/conf/httpd.conf was set to 4991 when it needed to be 4521.

    Resolution:
    In httpd.conf, change
    #ServerPort 4991
    to:
    #ServerPort 4521
