    I’ve got this when I switch from PHP 7.4 to PHP8

    Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/r60846/public_html/wp-includes/wp-db.php:1688 
Stack trace: 
#0 /home/r60846/public_html/wp-includes/wp-db.php(632): wpdb->db_connect()

#7 {main} thrown in /home/r60846/public_html/wp-includes/wp-db.php on line 1688

There has been a critical error on this website.

    I disabled plugins also, still in error.
    With the twentytwentyone default WP theme works like charm.

    How to fix that?

    Thank you!

    I forgot to mention that this problem is the same on several servers of different hosting providers. I am forced for this reason to stay at PHP 7.4

    We could not reproduce this issue, so we would like you to run some tests to help us pinpoint the problem.

    Your plugins list is missing from the System Info report.
    What plugins do you have installed?

    Try disabling all of your plugins and see if this issue persists.
    If it does not, then activate your plugins one by one (starting with Elementor), and see which plugin causes your issue.

    Please share the results of this procedure.

    As I said in the main post, this error is present if plugins are disabled.
    Right now, I installed a fresh WP on other server. No plugins! Same error.
    I sent an email to hosting support too.

    It seems, according to the hosts, that it does not support PHP 8, even if it is displayed in cPanel and available for selection. So I clarified and closed the topic. Thank you for your support!
