[Bogdans]

Hi
receive the warning when I click on the category, know someone who may be the cause?
It happens since I removed the language that I did import categories.

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/ritg1222/public_html/classes/MySQL.php on line 167

Thanks for any help

I am not what is cause of your problem, if possible it is better to find out the cause and solved the problem.
If everything looks fine, (all data is displayed correctly), then just ignore it.

But suggest to set to display_errors to 'off' if it is in production mode.

I do not know where this setting

Is there anything unusual? Or do you face any problems or issues except the errors?
If no, then just ignore it (and set display_errors to off), because I also see some error some places that won't affect the functionality.
