I get a 503 error when calling an include statement to another domain on my PLESK server in ModX e.g.
if (!@include_once (MODX_CORE_PATH . "model/modx/modx.class.php")){
//throw 503 error
}
Is this a CORS issue, or is something else making this if statement fail?
Thanks in Advance.
You need to update your open_basedir setting in plesk to allow domain1 access to domain2's directory structure:
http://php.net/manual/en/ini.core.php#ini.open-basedir
Depending on your host you may not be able to do this ~ quite likely not, that would be a pretty huge security problem. [in effect you could access & manipulate files on any domain on the server just by editing this setting]
