Hi @mahyulan ,
Glad you reached out! Happy to help.
You’re running into a bug that we’ve discovered recently wherein that specific error message that you pointed out is not a part of our POT file and is therefore not translating.
You can view the bug report in here — https://feedback.givewp.com/feature-requests/p/enable-translation-for-validation-error-messages.
I’ve added this ticket internally so that our product team can be made more aware of this issue. You can check out the link for any progress that our team has made on the issue.
Our feedback site is designed to be the single source for all updates on particular issues. If any movement has happened, it will be displayed there for both the public and our team internally.
If specific feedback only has a handful of votes, that influences the priority we place on it. The more votes, the faster things get worked on!
Currently, we also don’t have a workaround for this one at the moment. The good news is that it is only visual and will not prevent donations from coming through.
While our developers work on a fix, I’m here for further questions or other concerns!
I’m always happy to help!
