Checkbox Survey offers a feature that will allow you to lock your survey once you have started collecting responses. This feature is useful if you have multiple survey editors with access to the same surveys and you do not want to have respondents see different variations of the same active survey.
To enable this feature, visit your survey’s Properties page. Disable the option labeled ‘Allow editing of this survey while it is active and collecting responses’.
If you would like to enable this option globally on your installation, this can be done by visiting Settings – Preferences, and disabling ‘Allow Editing of Active Surveys’.
