Unable to connect to database !

[Aurel Klatik]

I have successfully updated from CPG 1.5.12 to 1.5.48 using PHP 5.3
In attempt to upgrade to CPG 1.6.26 I have uploaded files to server, changed server setting to PHP 8.3 and run webname/update.php
I was still logged in as webstie admin.  Got this error:

Coppermine critical error:
Unable to connect to database !

MySQLi said: 2054 : The server requested authentication method unknown to the client [mysql_old_password]

Have checked that MySQL is 5.5
I have no clue what to do. Can you please give me a hint ?

Take a look at your include/config.inc.php file and check all the setings are correctly pointing to your database. Once you have verified they are correct remember to run update.php as per the docs

https://coppermine-gallery.com/docs/curr/en/upgrading.htm

To run the PHP-file "update.php" (i.e. the update script), just enter the URL into the address bar of your browser. The file "update.php" resides in the Coppermine directory, so to run it you will need to point your browser to http://yourdomain.tld/your_coppermine_folder/update.php (if you have installed Coppermine into the root of your web site, you will have to run http://yourdomain.tld/update.php accordingly). This will update your Coppermine install by making all necessary changes in the database.
