Re: upgrade to 14 in linuxmint21 mysql error
You forgot to install the PHP mysqli extension.

Re: upgrade to 14 in linuxmint21 mysql error
hi,
your diagnosis is right. Thanks.
However, for the dashboard (administration) I got this:
"
Fatal error: Uncaught Error: Call to undefined function mb_substr() in /var/www/html/piwigo/admin/intro.php:397 Stack trace: #0 /var/www/html/piwigo/admin.php(346): include() #1 {main} thrown in /var/www/html/piwigo/admin/intro.php on line 397
"
piwigo/admin.php et /piwigo/admin/ come from the new version 14
I don't see where is the problem.
the rest of the gallery looks ok.
(additional note - not sure if this is the reason - : I encountered problems during the upgrade of lm20 to lm21 and apache2 did not work. I had to do sudo a2dismod php7.4 - sudo a2enmod php8.1 - systemctl restart apache2 and later sudo apt-get install php-mysql)
any help will be appreciated

Re: upgrade to 14 in linuxmint21 mysql error
You also forgot to install the PHP multibyte mbstring extension.

Re: upgrade to 14 in linuxmint21 mysql error
Use sudo apt-get install php8.1-mysql to install or enable the mysqli extension for PHP 8.1. Check that the PHP configuration file php.ini includes or loads the mysqli extension and after that restart the web server.
