Missing argument 2 for custominfobox()

[Guest]

Warning: Missing argument 2 for custominfobox() in /client/......./secure/includes/classes/boxes.php on line 124

 

 

I can see the code, but I cant see what function is calling it with the missing value.

 

Its when I click on a product to view the information about it.

 

sometimes that error comes up, it seems to be from something in product_info.php calling it, but im unsure.....
