I just installed the user panel on my production SMEServer (I'd alreadfy tried it on the test system), and httpd failed to come up properly.
It failed with
Oct 23 12:04:23 server01 httpd: Syntax error on line 2077 of /etc/httpd/conf/httpd.conf:
Oct 23 12:04:23 server01 httpd: syntax error in mask portion of network/netmask
Oct 23 12:04:23 server01 httpd-e-smith: Syntax error on line 2077 of /etc/httpd/conf/httpd.conf:
Oct 23 12:04:23 server01 httpd-e-smith: syntax error in mask portion of network/netmask
Oct 23 12:04:23 server01 httpd-e-smith: httpd startup failed
I looked at the relevant line and saw that an "external" host IP address was specified there, with a Mask of 255.255.255.255.
I edited this out, and then httpd started ok.
The comment on the server panel Security,local networks specifically recommends this mask, so I guess something is incompatible somewhere?
Luckily I can delete the remote network address, which I have done.
Cheers
