problem after server migration

[FreeBeeEssDee]

My coppermine was migrated from an old server with freebsd 12 and php 7.4 to a new machine with freebsd 13 stable and php 8.1. On the new server all other web applications (wordpress, nextcloud, postfixadmin, ...) are working smoothly. But coppermine throws the error:
Fatal error: Uncaught Error: mysqli object is already closed in /usr/local/www/coppermine/include/database/mysqli/dbase.inc.php:73 Stack trace: #0 /usr/local/www/coppermine/include/init.inc.php(172): CPG_Dbase->getError() #1 /usr/local/www/coppermine.3/index.php(22): require('...') #2 {main} thrown in /usr/local/www/coppermine/include/database/mysqli/dbase.inc.php on line 73

I tried the same coppermine from the old server, a freshly installed package from the ports and 1.6.20 and the development version from here. All with the same result. I successfully checked the database credentials by using the mariadb command-line tool.

It is likely the value for the database server that is causing an issue for you. Try using just 'localhost' for the database server.

Thanks for the hint and my fault that I forgot to include my config.inc.php:
cat config.inc.php

resolved?

No, I already used localhost and I have checked with "telnet localhost 3306" that the database can be reached.

[ron4mac]

Run the php command 'phpinfo();' and look at the mysqli section to see that it is configured properly.
Or try 'localhost:3306' as the database server in config.inc.php

[ron4mac]

In the file include/init.inc.php, on lines 172 and 173, change the 2 $CPGDB->getError() calls to $CPGDB->getError(false,true) to see if that gives you any better information.

Has this issue been resolved?
