In Virtualmin I checked the installation of LimeSurvey. It shows it being there, but also shows an incorrect password. This may be why I can no longer log in and instead get a message that states:
Internal Server Error
CDbConnection failed to open the DB connection.
An internal error occurred while the Web server was processing your request. Please contact the webmaster to report this problem.
How can I change the password that LimeSurvey is looking for? That is not an option in Virtualmin.
