Errors when we list products by manfact or search

Hi, I get this error at the top of the page when I try to list products by pressing on Manufactuers or when I do a search. The results display correctly, but I get this error at the top (just turn php errors off in php.ini?):

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in ......./public_html/devshop/templates/hot_cosmetics/html/com_virtuemart/category/default.php on line 44

Warning: Invalid argument supplied for foreach() in ......../public_html/devshop/libraries/joomla/html/html/select.php on line 536

Thanks.

That are warnings , just disable debugging.

Ivan, excellent news, but where is the debugging option to disable? You mean on vm or joomla? Because both are already off. Thnx

If you are running VirtueMart 2.0 on Joomla 2.5, please keep in mind it's not yet compatible with Joomla 2.5.

Running Joomla 1.7.3 and vm 2.0.0

Any ideas how to remove these debug errors?

Thanks

Global settings , system tab. If taht deos not help put this in index.php of template :

error_reporting(0);

after this line:
defined( '_JEXEC' ) or die( 'Restricted access' );
