PHP Fatal error: Cannot redeclare wp_unregister_GLOBALS()

[tchwpkgorg]

I'm not able to run wp-cli on some websites.

Running Wordpress 3.8.1 with wp-cli 0.13.0 and 0.14.0-beta.

I've checked the FAQ entry about a similar problem, and reported issue #288, but they don't seem to apply in this case.

Tried disabling the plugins, but it didn't help.

As far as I can see, it has something to do with the database.

Merely substituting these values with the ones from a website where wp-cli is working is enough to make wp-cli run:

define('DB_NAME', 'db_name');
define('DB_USER', 'db_user');
define('DB_PASSWORD', 'pass');

Any ideas how to debug this further?

Looking again at #288, can you post the full contents of your wp-config.php file (without any secret stuff)?

[tchwpkgorg]

Here it is:

Please note that identical file, but with only the following options hand-edited (so it uses credentials for a different wordpress, where wp-cli has no problems) just works:

Please let me know what happens when you run the following commands:

• wp core version
• wp --skip-plugins plugin status

I forgot to mention that the --skip-plugins flag only works with 0.14.0-beta.

Well, one way to debug this error would be to add the following code at the top of wp-includes/load.php:

debug_print_backtrace();

Other than that, I don't have any other suggestions. You have to figure out what's different between the installs that work and the ones that don't.

[scribu]

Or you could use the step-by-step debugger from XDebug (integrated into many editors, like NetBeans) to see exactly when the file is loaded a second time.

I guess that doesn't bring anything new?

I'm afraid not.

I got this now on my main local dev stack, think after I changed core source to dev repo. wp-cli cloned from git, works fine on other local sites. So it's some quirk in specific WP setup(s) that causes this.
