Hello!

I use maximenuCK with Virtuemart and params patch.

Too many errors:

This is a extract from server log:

[Sat Jul 06 13:28:23 2013] [error] [client xx.xx.xx.xx] FastCGI: server "/usr/sbin/php-xxxxxx" stderr: PHP message: PHP Warning: Creating default object from empty value in /var/xxxx/xxxx/xxxxxx/httpdocs/xxxxxxx/modules/mod_maximenuck/helper_virtuemart.php on line 274


The error_log from server have 878MB !!!! in 1 week !!
