 * Update of PHP doesn’t work on my site. I haven’t updated before because I have
   hardened PHP and it tells me I don’t need to. But now I cannot update wordpress
   or jetpack because I am using 5.4. I used PHP compatibility checker which said
   ok and so I changed to PHP version 7 on my c panel. Then I couldn’t log in to
   my site.
    error- Fatal error: Uncaught Error: Call to undefined function mysql_connect()
   in /home/granizcm/public_html/wp-includes/wp-db.php:1645 Stack trace: #0 /home/
   granizcm/public_html/wp-includes/wp-db.php(639): wpdb->db_connect() #1 /home/
   granizcm/public_html/wp-includes/load.php(435): wpdb->__construct(‘granizcm_wp569’,‘

   wp-admin/index.php(10): require_once(‘/home/granizcm/…’) #7 {main} thrown in /
   home/granizcm/public_html/wp-includes/wp-db.php on line 1645 I have gone back
   to my original PHP and now my site works but that leaves me unable to update.
   I struggle with these technical issues and would appreciate advice. Thank you
   Cathy
