mysql Fehlermeldung

[lukass2000]

Hallo Experten!

Bekomme seit heute folgende Fehlermeldung:

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /var/www/vhosts/xxxxx.xx/httpdocs/cpg/include/functions.inc.php on line 211
Fatal error :

Habe aber absolut nichts geändert.
Gester lief noch alles problemlos.
Was kann ich denn da machen?

DANKE!!!

Schalte debug_mode ein und poste die eigentliche Fehlermeldung (nicht den debug_output).

mySQL error:

Meintest du das?
DANKE!!!
