There is one other area which needs to be addressed which is the reference within Mantis to custom_strings_inc.php.
In the current setup it is assumed that these would be the same for all instances running of that singel install. This clearly is not de facto true.
Good news is that it is not a real issue anyway
This can be handled pretty easily, exactly in the same way as for the base config !!
Just move your custom strings into an instance dependent file caklled custom_strings_mantis1.php and so on.
Then your custom_strings_inc.php would look like :
<?php
// ******************************************************************************************
// * *
// * HTTP_HOST is used to determine the config file needed for webservices *
// * SCRIPT_NAME is used to determine the config file needed for commandline services *
// * *
// ******************************************************************************************
$hostheader = $_SERVER['HTTP_HOST'];
$mailscript = $_SERVER['SCRIPT_NAME'];
switch ($hostheader) {
case "mantis1.yourdomainl.com" :
include('custom_strings_mantis1.php');
break;
case "mantis2.yourdomainl.com" :
include('custom_strings_mantis2.php');
break;
}
switch ($mailscript){
case "read_mail_mantis1.php" :
include('custom_strings_mantis1.php');
break;
case "read_mail_mantis2.php" :
include('custom_strings_mantis2.php');
break;
}
The same applies for the custom_constants_inc.php
@phileas,
did not add that to the wiki, did not want to screw up your very nice lay-out

. So please add the above to the Howto.
