Blank screen after Transplant Module

[Javi Ferrer]

I'm trying to move a module from hook left column to footer. I use the follow code:

    public function hookdisplayFooter($params){
        return $this->hookDisplayLeftColumn();
    }

So, I can move the module with no problem but a blank screen show when I refresh the shop. I activated the developer mode on defines.inc.php file and I get thie follow:

 

 

 

Fatal error: Call to undefined method BlockAdvertising::hookDisplayLeftColumn() in /home/user_folder/public_html/shop/modules/blockadvertising/blockadvertising.php on line 292

 

 

Te line 292 refer to code inserted but I don't find where is the mistake.

 

 

Do You have any idea what happen?
