First of all, since I am a new member I thank you all in advance for your help and you patience if my question is easy to fix.
I customize my CSS Template and created many survey. I would like to be able to rename some {QUESTIONHELP} answers.
Example : "Please select at most one answer" (which is the Hint displayed if a multiple question set with a maximum of 1 answer is selected) and rename it differently.
I would like to do it in the Template in order to inherit this update to all of my survey.
Is there a way to do it and could you please explain me how ?
Standard texts like these are included in the "locale" files in your LimeSurvey installation.
You need an editor like poedit to change them - and take care to include your changed translations to any update you may install locally. I think you can find more information on this website about translations under Community or The Project.
