[parts]

Hi,

I hope somebody can help me here. I am totally not experienced with technical issues in Magento. I receive an error starting my site. Someone similar with this issue? Hope you guys can get me online!

Error:

Fatal error: Undefined class constant 'CACHE_GROUP' in /home/deb126395/domains/lapparts.nl/public_html/app/code/core/Mage/Core/Block/Abstract.php on line 1075

Hi @parts 

Can you check in your Abstract.php file if below code is present at line 46.

const CACHE_GROUP = 'block_html';

If it is not present then please add this code at line 46.

Hope it helps you!

Thanks

Thanks Rahul for your reply.

The code is not missing, see below.

abstract class Mage_Core_Block_Abstract extends Varien_Object
{
/**
* Prefix for cache key
*/
const CACHE_KEY_PREFIX = 'BLOCK_';
/**
const CACHE_GROUP = 'block_html';
/**
* Block name in layout

It says it gives a problem at line 1075.
