Errors like this are logged. Check the error log on your server. If you can’t find the log, please contact your host.

Meantime, enable wp_debug and wp_debug_log and after an error, look at wp-content/debug.log to see if anything gets logged there. https://www.ads-software.com/support/article/debugging-in-wordpress/

Let’s focus on Uncaught Error: Call to undefined function wp() in /home/u12515p9108/domains/vcwaterland.nl/public_html/wp-blog-header.php:16\nStack trace:\n#

I have updated the core files but still get the error.

send_origin_headers should be in wp-includes/http.php. Is that file there and readable?

Thread Starter

(@jesse120502)

This is in the http.php file:

function send_origin_headers() {
	$origin = get_http_origin();

	if ( is_allowed_http_origin( $origin ) ) {
		header( 'Access-Control-Allow-Origin: ' . $origin );
		header( 'Access-Control-Allow-Credentials: true' );
		if ( 'OPTIONS' === $_SERVER['REQUEST_METHOD'] ) {
			exit;
		}
		return $origin;
	}

	if ( 'OPTIONS' === $_SERVER['REQUEST_METHOD'] ) {
		status_header( 403 );
		exit;
	}

	return false;
}

See https://www.wpbeginner.com/plugins/how-to-deactivate-all-plugins-when-not-able-to-access-wp-admin/

This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

(@jesse120502)

I tried to disable all plugins but i still dont have access to my admin panel.

If you don’t mind, i can also give you the login details to my ftp server and admin panel. I would be really helpful if you could take a look there if you can fix it ??

Please don’t offer to send or post logon credentials on these forums: https://www.ads-software.com/support/guidelines#the-bad-stuff

You may trust me, but it normalizes a dangerous practice. It’s a fine line, but one that we need to enforce. Thanks for your cooperation. Never give anyone access to your site without a signed, enforceable contract. I’m not willing to do that, nor could you afford me. ??

Let’s start again with the reinstall. Delete all “loose” PHP files in the root of your site, except wp-config.php, and remove the directories wp-admin and wp-includes, then do the manual installation again: https://www.ads-software.com/support/article/updating-wordpress/#step-1-replace-wordpress-files

Okay the site works now! I disabled all plugins and am now enabling them 1 by 1. I get the http 500 error when i activate the classic editor plugin from wordpress.

I just tried it again and I actually get the error when i enable more than 3 plugins.
