Hello @mark
I do not see where you have replaced:
@KALTURA_VIRTUAL_HOST_PORT@
with your port number for the virtual host you set in configuration. This is usually port [80].
Nor, have you replaced the path to the Kaltura log and app folder tokens:
@LOG_DIR@ this is usually /opt/kaultura/logo/
@APP_DIR@ this is usually /opt/kautura/app/
If you did not properly update those tokens found in the file with valid information then try that and restart HTTPD.
