Tsv/csv exports not functioning

Why can’t i export my information? Im trying to export my costumers into a file so i can manipulate with excel to keep an organized backup of my database.

Every time I click on the export button no download begins it just opens up a new html page with all the costumers in one single page.

It used to be working perfectly…??

Attach screenshot.

It isn’t supposed to download anything. The Export function opens a window for copying. Read about it here: Manager Cloud.
