Delete the runtime folder and reload it.

Error message: undefined variable _ v
It should be caused by the $ s_category_info variable being false or null. Print it on the Controller to see if there is any data retrieved from the data table.

Is it because your writing is not standard?

 
  
{$ K}
  
------ Solution ----------------------
  
{$ Vo}
  

 

Yours is

{foreach from=$s_brand_info key=_k item=_v}
   {$_v.brand_name}
{/foreach}
