I'm using BL_CustomGrid extension for customising admin grid, when I filter products grid by categories it throws me the error below, I couldn't find out how to diagnose the problem, if anyone has an idea I would really appreciate it.

Thank you

enter image description here

 a:5:{i:0;s:43:"Invalid attribute name: blcg_custom_field_1";i:1;s:7372:"#0 /app/code/core/Mage/Eav/Model/Entity/Collection/Abstract.php(1291): Mage::exception('Mage_Eav', 'Invalid attribu...')
Mage_Eav_Model_Entity_Collection_Abstract->_addAttributeJoin('blcg_custom_fie...', 'inner')
Mage_Eav_Model_Entity_Collection_Abstract->_getAttributeConditionSql('blcg_custom_fie...', Array, 'inner')
Mage_Eav_Model_Entity_Collection_Abstract->addAttributeToFilter('blcg_custom_fie...', Array, 'inner')
Mage_Catalog_Model_Resource_Product_Collection->addAttributeToFilter('blcg_custom_fie...', Array)
