I downloaded the shrines Blue Design Business Plan II and II, I have installed one by one and when I select any templates by default as I get the following error occurs:
Fatal error: Call to a member function Header () on a non-object in / home/soluc102/public_html/pruebas/templates/blue_design_ii/index.php on line 21
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<jdoc:include type="head" />
<?php
$this->helix->Header()
->setLessVariables(array(
'preset'=>$this->helix->Preset(),
'header_color'=> $this->helix->PresetParam('_header'),
'bg_color'=> $this->helix->PresetParam('_bg'),
'text_color'=> $this->helix->PresetParam('_text'),
'link_color'=> $this->helix->PresetParam('_link')
))
->addLess('master', 'template')
->addLess( 'presets', 'presets/'.$this->helix->Preset() );
?>
</head>
How can I fix the error.
Note: The installation was without the sample data.
