jQuery not loading in Admin.

[willhaynes24]

I was encountering an odd bug after updating to the newest nightly.

It appeared that no js scripts were being loaded by load-scripts in wp-admin. Since CSS was obviously being included, I compared load-scripts.php and load-styles.php and found what appears to be a missing directory separator.

Changing

define( 'WPINC', 'wp-includes' );

to

define( 'WPINC', '/wp-includes' );

in wp-admin/load-scripts.php seems to have fixed the problem. I'm not sure if this is the correct fix, but I did find it odd that load-scripts.php used different syntaxes to include their respective filenames:

from wp-admin/load-scripts.php:

require(ABSPATH . WPINC . '/script-loader.php');
require(ABSPATH . WPINC . '/version.php');

and from wp-admin/load-styles.php

require(ABSPATH . '/wp-includes/script-loader.php');
require(ABSPATH . '/wp-includes/version.php');

This is working for me on a vanilla install of 3.6-beta3.

The ABSPATH variable in that file has a trailing slash added so when the variables get concatenated further down the slashes are all present an in the right places with the current code.

Are you running any other plugins on this testing site? Maybe one of them is affecting script loading.

Feel free to reopen with the steps to reproduce on a clean install if there's still a problem.

Hey,
That report shows an error for usage of deprecated/removed function in jQuery. Please try support forums first and if it's an error then create a new trac ticket for it with the errors you have.
