One of my sites has a URL that is currently giving a 500 error, and I happened to notice that it says to contact the server administrator at a wacky email address. I am using WHM and cPanel to run several different virtual hosts on a single machine, and I'd like to set it in a way so that it won't be overwritten when some other change is made via those. And, preferably, for all virtual hosts in a single place, rather than individually for each (I want to use the same admin email address for all of them).
I went to update it to something meaningful, but I've thus far been unable to even find how it's being set. I believe I've found where it's being set: There's a cp_errordocument.shtml thing which is sourced into various error pages, and it seems to be using $SERVER_ADMIN -- presumably an environment variable? -- to populate the displayed email address.
When I log in at the command line, $SERVER_ADMIN is unset (or maybe empty).
In WHM, under "Home" / "Server Configuration" / "Basic WebHost Manager Setup" / "Contact Information", I have set both "one or more email addresses to contact in case a problem arises with this server" and "one or more cellular phone or pager email addresses to message via email in case a problem arises with this server" to the appropriate email address. This did not help.
Also did so under "Home" / "Server Contacts" / "Contact Manager" / "Email". Also did not help.
"Home" / "Service Configuration" / "Apache Configuration" / "Include Editor": I put a ServerAdmin directive into each of the three files pre_main_global.conf, pre_virtualhost_global.conf, and post_virtualhost_global.conf. Did not help.
Also in those three files, I tried putting SetEnv directives for SERVER_ADMIN. WHM errored out on this attempt.
I've tried a bunch of other things that I forget, and have spent considerable time poking around all sorts of settings in both WHM and cPanel, plus searching online, all to no avail.
I've done things like restarting Apache.
I should note that I do not absolutely know that the message is coming from cp_errordocument.shtml, but the contents of that file sure look like they'd produce the output.
Anybody know how I can resolve this?
