Lime survey worked perfectly fine before, but right after I upgraded MySQL, it failed with the following error message when it execute either index.php or admin.php:
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.
I rebuilt the database, but it didn't help.
I reinstall liner survey in another folder, and it gives the same error message.
I don't know how it is broken, because I have another lime survey installed in another folder, and it works perfectly fine.
