WordPress Installation Error

[Benjamin_Zekavica]

On all my new project I have this error message if I want to install WordPress:
Fatal error: Uncaught Error: Call to undefined function wp() ..... wp-blog-header.php on line 16

Please fix it.

Hi @Benjamin_Zekavica, welcome to WordPress Trac! Thanks for the report.

In #44480 you mention creating a wp-config.php file. Does the issue happen with the file you've created manually, or with the file created by the WordPress installer?

I can only reproduce the error if I create a file without the necessary lines at the end, see wp-config-sample.php​:

/** Absolute path to the WordPress directory. */
if ( ! defined( 'ABSPATH' ) ) {
	define( 'ABSPATH', dirname( __FILE__ ) . '/' );
}

/** Sets up WordPress vars and included files. */
require_once( ABSPATH . 'wp-settings.php' );

Could you make sure these lines are present in your wp-config.php file?

Thank your @SergeyBiryukov :)
This bug cames with wp 4.9.6 - in different versions I dont have any problems.

After I upload WP Files on server i open the path of the installation in the browser - normaly cames a installation screen but for still 7 Weeks I have alwasy this bug.

I have try it on local machine and a live server its a same error message.
More and more my friends who works with WP say this error with the new version.

To fix it i create manually a wp-config.php and copy the code for example config. Than it works. But the installer message dont came direcly.

I hope it can be fixed.

Best wishes from Germany :)

Hello @Benjamin_Zekavica,

Are you still having this problem? Were you able to check if the lines Sergey noted previously are at the end of the wp-config.php file?

Closing due to inactivity and that this appears to not be a valid issue.
