Hi everyone. I’m currently working with LimeSurvey and would appreciate some guidance.When respondents (youth users in our case) complete a survey and later click the same survey link again, they are shown a page with the message:“Error – You have already completed this survey.”From a user experience perspective, we’d prefer this message to be more positive — for example, replacing “Error” with a “Thank You” message, since the user has already successfully completed the survey.Is it possible to configure this behavior from the admin side?
Specifically:

• Can the “Error” message be customized or overridden?
• Is there a way to redirect users who have already completed the survey to a custom “Thank You” page instead?
