 * Hi,
 * This erroe appeared on the top of my site.
 * _Warning: Array to string conversion in /home/klimatis/public\_html/wp-includes/
   pluggable.php on line 2279_
 * I have checked line 2279: $nonce = (string) $nonce;
 * Full code:
 *     ```wp-block-code
       if ( ! function_exists( 'wp_verify_nonce' ) ) :
       	/**
       	 * Verifies that a correct security nonce was used with time limit.
       	 *
       	 * A nonce is valid for 24 hours (by default).
       	 *
       	 * @since 2.0.3
       	 *
       	 * @param string     $nonce  Nonce value that was used for verification, usually via a form field.
       	 * @param string|int $action Should give context to what is taking place and be the same when nonce was created.
       	 * @return int|false 1 if the nonce is valid and generated between 0-12 hours ago,
       	 *                   2 if the nonce is valid and generated between 12-24 hours ago.
       	 *                   False if the nonce is invalid.

       		if ( ! $uid ) {

       		if ( hash_equals( $expected, $nonce ) ) {
       			return 1;
       		}
   
       		// Nonce generated 12-24 hours ago.
       		$expected = substr( wp_hash( ( $i - 1 ) . '|' . $action . '|' . $uid . '|' . $token, 'nonce' ), -12, 10 );

 * Try [manually resetting your plugins](https://wordpress.org/support/article/faq-troubleshooting/#how-to-deactivate-all-plugins-when-not-able-to-access-the-administrative-menus)(
   no Dashboard access required). If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, access your server via [SFTP or FTP](https://wordpress.org/support/article/ftp-clients/),
   or a file manager in your hosting account’s control panel (consult your hosting
   provider’s documentation for specifics on these), navigate to /wp-content/themes/
   and rename the directory of your currently active theme. Hopefully, this will
   force the default theme to activate and rule out a theme-specific issue (theme
   functions can interfere like plugins).

 * Thank you very much for the answer.
 * It turned out **Page scroll to id** plugin causing the problem.
 * Is there anything I can do?

 * I recommend reporting the issue at [https://wordpress.org/support/plugin/page-scroll-to-id/](https://wordpress.org/support/plugin/page-scroll-to-id/)
   so the plugin’s developers and support community can help you with this.
