Welcome to the forums.
Limesurvey has been recommended as one of the systems that one can use with Prolific in the past when there was a list of compatible survey systems. This is from the Google cache
The FAQ no longer mentions a list of systems, but there is no reason to believe afaik that Limesurvey has stopped working.
I tried a LimeSurvey URL that I googled.
And entered it into a draft survey and previewed it, and Prolific allowed me to jump to the start page of the Limesurvey survey.
Is your LimeSurvey URL in a similar form at the one above (starting with “https://” and ending in something like “.php/123456?lang=en” ?
Would it be okay for you to share it with us?
