Hi I get sometimes an error using the search sidebox.

the message is:

Warning: Variable passed to each() is not an array or object in /mounted-storage/home16b/sub001/sc18116-VNPY/luxim/includes/application_top.php on line 712

Warning: Cannot modify header information - headers already sent by (output started at /mounted-storage/home16b/sub001/sc18116-VNPY/luxim/includes/application_top.php:712) in /mounted-storage/home16b/sub001/sc18116-VNPY/luxim/includes/functions/functions_general.php on line 53

This only happens is there is no valid seach result.

The site is at
http://www.luxim.nl

In the header seachrbog there is no error:S
Any suggestion how to solve this?
