• 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
