Hello,
Thank you for reaching out to us.
Translation files of the theme should be placed in /wp-content/languages/themes/ folder,
plugins, like Core plugin, in /wp-content/languages/plugins folder (this is System location),
with correct names, for example, for XStore theme: xstore-es_AR.po, and xstore-core-es_AR.po for XStore Core plugin, then you will not lose translation after the update – https://www.8theme.com/documentation/xstore/theme-translation/base-theme-translation/
We would recommend doing a backup of all the files before any update https://www.8theme.com/documentation/xstore/theme-installation/theme-update/
Also, after every update, you need to synchronize translation – https://www.8theme.com/documentation/xstore/theme-translation/translation-files-update/ Sometimes new strings are added, and only after synchronization, you’ll be able to translate new strings or strings that were changed. Not always, but some strings can be missing after the sync and you need to find and translate them one more time, this is independent of us and relates to WP functionality.
Could you please provide temporary wp-admin access? We need to check your settings.
To grant WP-Admin access, please proceed to create a new user account with an administrator role through your WordPress Dashboard. Once the account is established, you may securely transmit the username and password to us via the Private Content section designated for this purpose.
Best Regards,
8Theme’s Team
