Hi:
The translation site is a completely different installation and we would need to add a login for you – this prevents random folks from going in and messing with the translations.
But, if you want the POT files to translate them and then send back to us you can download them direction from the site.
For example, if you want the POT file for reboot, you can navigate to the german terms page and use the EXPORT link at the bottom.
I.e.: TranslationSiteHome->Access Translations->Simple Press Themes->Reboot->Version 2.0->German
That navigation sequence would take you to this page: https://glotpress.simple-press.com/glotpress/projects/simple-press-themes/reboot/version-2.0/
After downloading the pot file from there, you can click the PROJECTS link at the top of the page and then click on the Simple:Press Core link.
Once you’ve completed the translations, you can send the PO files to us and we’ll upload them to the site for everyone to use.
Thanks.
