I just update the Product Sale and Cost Price to last version and I now get's this error then I try to enter the setting of all your modules I have.
There is a problem in your /home/vmoc5b9v/public_html/system/mysqli.php database file, it contains sql mode with 'NO_ZERO_DATE'. Please remove this part of the sql mode and try again. Click here to go back.
All modules was working before the update.
