DeMomentSomTres Export was build because DeMomentSomTres had a customer with a very big blog that had to be imported with all attachments.
This plugin is a modified version of the export procedure.
Standard export procedure can be recovered unistalling or deactivating this plugin.
More information: http://demomentsomtres.com/en/wordpress-plugins/demomentsomtres-wordpress-export-post-with-images/
I have activated the plugin and NOTHING happens
This pluguin ONLY modifies some elements in the internal processes of WordPress Export so no apparent changes will be seen by the users.
Go to Tools > Export and use it.
This problem has been solved in version 2.1.
