phpMyAdmin - problem s updatem

Dobry den,

toto mi hlasi phpMyAdmin, kdyz aktualizuji radek v databazi:

Warning: Invalid argument supplied for foreach() in /home/web/wz.cz/mysql/tbl_replace.php on line 132

Warning: Cannot modify header information - headers already sent by (output started at /home/web/wz.cz/mysql/tbl_replace.php:132) in /home/web/wz.cz/mysql/libraries/common.lib.php on line 1332

Cili nejde mi provest zadna zmena timto zpusobem (jiny momentalne nepouzivam).
Hlasi mi to u vsech tabulek. Vkladani funguje.

Diky za jakoukoliv radu
