LimeSurvey version: Community Edition Version 6.3.9+231211 Own server or LimeSurvey hosting: Own server Survey theme/template: Fruity TwentyThree
==================
The survey seems to work for many. But the response rate is much lower than last year before I did the latest update. May be due to a survey participant noting me that he received the following message:
"CDbConnection is unable to find PDO class "PDO". Make sure PDO is installed correctly."
Does anyone else have this problem and what can be done about it?
