Marius (Clorith) on "Error 500 after last WP update"

I am having a problem loading our website. The error received: Waing: require(/home/verifres/public_html/wp-includes/load.php): failed to open stream: No such file or directory in /home/verifres/public_html/wp-settings.php on line 21

Fatal error: require(): Failed opening required '/home/verifres/public_html/wp-includes/load.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/verifres/public_html/wp-settings.php on line 21.

Any ideas how to restore the site?

Try this first, change the PHP version from 5.3 to 5.4 or higher. Sometimes, thats the cause.

See if you have the right permission of your load.php (should be 644) under the wp-inlcudes folder.

if not, you may need to reinstall the WordPress.

Thanks, will check.

Am now receiving the following error after restoring our website to an earlier state:
Fatal error: Class 'WC_Payment_Gateway' not found in /home/verifres/public_html/wp-content/plugins/woocommerce-paypal-pro-payment-gateway/woo-paypal-pro-gateway-class.php on line 3

Have you increased the PHP version already?

If so, post your issue to the plug in author so they can check it.

Hiya,

For your original issue, this is a symptom of an update that's failed while copying new files, so your installation is now missing some core files, this can be resolved by following the manual update steps found at https://codex.wordpress.org/Updating_WordPress#Manual_Update

As for your current issue, it sounds like the WooCommerce plugin might not be activated on your site?
