I get the following warning in my WP debug log:
[04-Nov-2021 08:20:49 UTC] PHP Warning: file_exists(): open_basedir restriction in effect. File(/var/www/clients/client1/web19/web/wp-content/db.php) is not within the allowed path(s): (/var/www/clients/client1/web19/web:/var/www/clients/client1/web19/private:/var/www/clients/client1/web19/tmp:/var/www/example.com/web:/srv/www/example.com/web:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/dev/random:/dev/urandom) in /var/www/clients/client1/web19/web/wp-includes/load.php on line 545

However, when I check my ISPConfig control panel Domains >> Websites >> Options >> PHP open_basedir: I have:
/var/www/clients/client1/web19/web:/var/www/clients/client1/web19/private:/var/www/clients/client1/web19/tmp:/var/www/example.com/web:/srv/www/example.com/web:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/dev/random:/dev/urandom
Which clearly shows that /var/www/clients/client1/web19/web/wp-content/db.php is inside of an allowed directory?
Any have any suggestions on how I should resolve this?
The solution that I have was to restart mysql, which I tried, but the problem persists.
