CiviCRM Community Forums (archive)

In this documentation:
http://wiki.civicrm.org/confluence/display/CRMDOC/Multi+Site+Installation

it's suggested using home_url() as the base url in the settings file.
we ran into an issue because using that function assumes WP has been instantiated. but there are a number of places where civi pulls resources outside of WP. for example, a contribution page widget, which needs to be standalone.

I fixed by wrapping in a function_exists() condition, and reverting to a fixed URL if it does not. just curious if others have found a better solution or if there are any gotchas with the above.
