I've browsed through quite a few similar questions, but many of these seem to have gone unanswered. I have some new input that might help.


I'm running EE2.5.5, Assets 2.05, and Multiple Site Manager (not sure if version is relevant/where to find it) with 3 custom sites.

Like most similar questions, everything seems to be working fine on the default site (let's call this one Site1). Every site had their File Upload Directories duplicated from Site1 and are working fine in EE's own File Manager (after syncing every directory).

The Problem

Assets is not working in any of the site variations.

What's interesting: I know why! The "Update Indexes" feature is failing. When I hit "Update Indexes", an AJAX request is made to the wrong domain. This request SHOULD go to "site1.com/", instead of "site2.com/", since the control panel only works from site1 (in my setup).

I've tried adding the config variable $config['assets_site_url'] = 'http://site1.com/index.php';, unfortunately to no avail.

The Question

How/where can I configure Assets to help it send the Update Indexes AJAX request to the correct URL?

This was solved by adding $config['assets_site_url'] = 'http://site1.com/index.php'; for real - on the first try something had went wrong for Adrian silently, apparently.

Using the CP to add this option worked as expected.

    I figured out what went wrong, the first time: I had to define it as http://site1.com/ instead of http://site1.com/index.php, since we removed the "index.php" from the URL's as described in this manual: ellislab.com/expressionengine/user-guide/urls/… Thanks Andris!

  • Some Notes that might help someone: this thread led me to try a few things. I got this to work slightly different method. added: $config['assets_site_url'] = '/index.php'; AND $config['assets_cp_path'] = '/admin.php'; of the main site's config file ONLY (not to the msm sites). Also check the head of that file as assets may have already written to it. EE2.7.3 + Assets 2.4
