I seem to be unable to import a .po file I have created for my custom module.
Using D7.44 and Commerce Kickstart (commerce_kickstart-7.x-2.38)
When I go to /admin/config/regional/translate/import and select my .po file I get the following messages:
For security reasons, your upload has been renamed to commerce_stripe.de_.po.txt.
The specified file commerce_stripe.de_.po.txt could not be uploaded. Only files with the following extensions are allowed: po.
File to import not found.
