Upgrade survey-01 to PHP 8.2
Currently, LimeSurvey supports PHP up to 8.1, whereas Debian bookworm ships (and supports) only version 8.2.
One forum post suggests PHP 8.2 will be supported with the next major release, which should be LimeSurvey 7.
For the moment, we've kept PHP 7.4 on survey-01
, supported by bullseye-security releases.
