Hello good people of Stack Exchange.

Our small business has recently transferred our website to a new Magento hosting agency and we are experiencing an issue with the functionality for exporting customer information.

The process should be straight-forward:

http://www.magentocommerce.com/knowledge-base/entry/exporting-product-or-customer-information

However, when we select the entity type from the drop-down menu the page hangs on the 'Please wait...' message and the following error message appears:

Source model "donation/eav_attribute_source_giftaid" not found for attribute "giftaid"

We are a retail business so a giftaid message (which I assume relates to a charity setup) makes little sense to us.

We have flagged this issue with our agency but they haven't provided us with an answer and we need to get this functionality working.

If anyone with Magento experience could shed some light on the situation and offer any potential fixes it would be greatly appreciated.

Many thanks all!
