Hello,
If it is only related to WPCA, and if you managed to translate other plugins, I would first recommend you disable any plugin except WPCA and Loco Translate, and try again.
What are the results about this?
You might probably want to post the issue you are getting with Loco Translate on the Loco Translate support forum.
Did you ask anything to Loco Translate about an issue you are getting with their plugin? We are following WordPress practices for internationalisation and string translations. We’re not doing anything special. Just loading translation files with WP standard functions. So they might probably give a better help than us.
At last but not least, is Loco Translate actually giving you any information on the language file you are actually editing?
Our main plugin is actually including some language files, stored in wp-content/plugins/customer-area/languages, but they are NOT loaded by default (they are just there in case you want some default languages files, not already translated by the WP community, and start over). By default, the loaded languages files are being downloaded from WP.org, and will be located in wp-content/languages, so you might probably be editing some languages files that are not being loaded. I don’t know how Loco Translate works, but you have to translate WPCA languages files from the wp-content/languages directory. You can also copy WPCA languages files to wp-content/customer-area/languages, and those ones will be loaded instead, so you can make your own edits, without Loco Translate, but by using PoEdit for instance.
Also, downloading files from WP requires that you first select your main language in wp-admin > settings > general, and that you then download the languages files for your plugins. This can be done on wp-admin > Update > Update languages (button at the bottom of the page).
Regards.
