Magento – Column ‘option_id’ in where clause is ambiguous.

This problem should be fixable by changing app/code/core/Mage/Eav/Model/Resource/Entity/Attribute/Option/Collection.php line 117. Just insert “main_table.” (without “) before option_id. The line shoul look like the following after that:

return $this->addFieldToFilter('main_table.option_id', array('in' => $optionId));
