Problem

When accessing API Portal page or API Portal administration page in Joomla, "Error" message is thrown and no other output, nor login page.

Apache logs:

==> /var/log/httpd/access_log <==

10.10.10.10 - - [31/Jan/2019:11:16:10 -0500] "GET /administrator/index.php HTTP/1.1" 500 5 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0"

Resolution

This due that the database is stopped.

The solution is to:

• start the database,
• make sure that is reachable,
• restart API Manager and
• recheck.
