I'm trying to export all the information k2 but does not work, it does not export anything

Hello Juan,

K2 does not offer export functionality, you need a 3rd party extension in order to migrate it to another environment.

this button to it?

This is a 3rd party extension, you need to address this issue to the the extension's developer.
