WP Editor error

  • Hello,

    WP editor is not working to create pages/posts. Debug mode throws this:

    `Error notice: Undefined property: wpdb::$dmtable in /home/rabbitr1/public_html/wp-includes/wp-db.php on line 648

    Warning: Cannot modify header information – headers already sent by (output started at /home/rabbitr1/public_html/wp-includes/wp-db.php:648) in /home/rabbitr1/public_html/wp-includes/functions.php on line 6584

    Warning: Cannot modify header information – headers already sent by (output started at /home/rabbitr1/public_html/wp-includes/wp-db.php:648) in /home/rabbitr1/public_html/wp-admin/includes/misc.php on line 1310

    Warning: Cannot modify header information – headers already sent by (output started at /home/rabbitr1/public_html/wp-includes/wp-db.php:648) in /home/rabbitr1/public_html/wp-admin/admin-header.php on line 9`

    And admin-header.php file on line 9 says:

    header( ‘Content-Type: ‘ . get_option( ‘html_type’ ) . ‘; charset=’ . get_option( ‘blog_charset’ ) );
    if ( ! defined( ‘WP_ADMIN’ ) ) {
    require_once __DIR__ . ‘/admin.php’;
    }

    There′ve been no changes in theme and plugins:

    – WP v5.8
    – Hello Elementor theme v2.4.1
    – Elementor 3.3.1
    – Elementor Pro 3.0.5

    What had caused this error?

    Regards,

    Julia

    Hello @t-p,

    There′s no spaces, new lines, or other stuff before an opening <?phptag or after a closing ?> tag in wp-dp.php.
