I want to translate the plugin, but I can’t find the PO/MO file

I want traslate the plugin to Portuguese too, so if add this option will help a lot.
Try use the system tralations of wordpress, this will make the things more easy to translate and get traslations of all others languages.

When there are no translations available or you need to change the actual wording of certain phrases use this:

Hi there,

I managed to translate the frontend text of this plug-in with WPML. This is a paid plug-in for having a multilanguage website. I now have English, Dutch and German. Just look for WPML > String Translation > Translate texts in admin screens (end of String Translation page) > search for wpcr3_options > templates

The only strings I could not translate are the texts message that shows after hitting the submit button. For example:
“You did not pass our human detection check.” or “Thank you! Your review has been received and will be posted soon.”

Hope this helps for you or others!

An addition to above message:

I managed to translate/edit the texts that show when you hit the submit button:

Go to \wp-content\plugins\wp-customer-reviews\js

And open the wp-customer-reviews.js with Wordpad. Now you can edit the messages. If you want a line break, use \n between sentences.
Example:

Vink het vakje aan om te bevestigen dat u een mens bent.\nYou must check the box to confirm you are human.\nBitte markiere die Checkbox, um zu bestatigen, dass Sie ein Mensch sind.

Good luck!
