Fatal error after upgrading to PHP 7.3

  • After upgrading to PHP 7.3 (prior PHP 7.2.25) the apparence of my site is:

    Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/jrrduzqv/public_html/wp-includes/wp-db.php:1665 Stack trace: #0 /home/jrrduzqv/public_html/wp-includes/wp-db.php(632): wpdb->db_connect() #1 /home/jrrduzqv/public_html/wp-includes/load.php(425): wpdb->__construct(‘jrrduzqv_dbbbcm’, ‘Z8pS6]]v1H’, ‘jrrduzqv_dbbbcm’, ‘localhost’) #2 /home/jrrduzqv/public_html/wp-settings.php(116): require_wp_db() #3 /home/jrrduzqv/public_html/wp-config.php(85): require_once(‘/home/jrrduzqv/…’) #4 /home/jrrduzqv/public_html/wp-load.php(37): require_once(‘/home/jrrduzqv/…’) #5 /home/jrrduzqv/public_html/wp-login.php(12): require(‘/home/jrrduzqv/…’) #6 {main} thrown in /home/jrrduzqv/public_html/wp-includes/wp-db.php on line 1665

    Do I need to talk to my webmaster, or is there something wrong?

    Thanks for the help and sorry for my English.

    I talked to my webmaster ;-), the extensions “mysqli” and “pdo_mysql” in the “base release” of PHP 7.3 are not released, I have activated the extensions “nd_mysqli” and “nd_pdo_mysql” and, for now, the problem seems having resolved.

    Bingo.

    Had exactly the same issue. Two new installs of WP (5.4) on PHP 7.2. Went to change the PHP Version via Cpanel and ran into this message.

    Enabled 7.3 again and these two weren’t ticked. Ticked them and it seems to be working fine.

    Edit: Checked with my host and these aren’t enabled by default because not all Applications need them? They’re reviewing this. Seen as WP recommends 7.3. If someone enables 7.3 and runs into the issue above, they may not be able to resolve it easily.
