An Attribute error when export products in Magento1

[vaguemind]

I am trying to use data flow option export for exporting products in Magento ver. 1.9.0.1

but and error appears like below :

Source model "ves_brand/system_config_source_ListBrand" not found for attribute "vesbrand"

i tried to check eav_attribute table in the db but i couldn't find any attribute with name "vesbrand" to remove it but i couldn't find it ?!

could someone help me ?

Please note that Magento cannot read model files that have any capitalization other than at the start. Aka Testvariable.php works but TestVariable.php will cause it to fail to find. In your case the file name is ListBrand.php so please change it to Listbrand.php and then try.

Apart from this if you are not using any attribute which is using Source model "ves_brand/system_config_source_ListBrand" then run this query to delete those attributes 

To verify :

select * from eav_attribute where source_model = 'ves_brand/system_config_source_ListBrand'

To remove attribute:

delete from eav_attribute where source_model = 'ves_brand/system_config_source_ListBrand'
