but these table is empty, and per command i can write in, also with duplicate keys, in old mode and insert ignore into...

all what i could check and change does not play any role at all. as well i testet the engines innodb, and MyISAM, it never worked. But only on an old mysql 5.0.67-log SUSE MySQL RPM it works without any problem.

my settings therfore are in my.cnf

old_mode = NO_DUP_KEY_WARNINGS_WITH_IGNORE,ZERO_DATE_TIME_CAST

## sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

# sql_mode=NO_ENGINE_SUBSTITUTION

# sql_mode=ALLOW_INVALID_DATES,MYSQL40,NO_KEY_OPTIONS,NO_TABLE_OPTIONS,TRADITIONAL,ANSI_QUOTES,HIGH_NOT_PRECEDENCE,IGNORE_BAD_TABLE_OPTIONS,MAXDB

sql_mode=MAXDB

I tested setting for setting, but ist does not change anything.

the client site is cacti boost plugin on PHP Version => 5.2.6

where can i get an usfull error message with gives me a hint what is going wrong and what cat i setup to become it compatibel with the old mysql

thanks Siegfried
