Recently my web host updated PHP, and now my limesurvey install is inaccessible (Internal Server Error). They required new password on all databases. How do I reset my configuration with a new password?

Database config is in file application/config/config.php

Thanks (I'm a bit rusty with Limesurvey) - I saved the new config with a new password. I'm still locked out.

Screen-shot of error message please.
Also set debug = 2 in your config.php.

Thanks for that. There are 4 errors:

throw new CDbException('CDbConnection.connectionString cannot be empty.');

391 $this->_pdo=$this->createPdoInstance();
392 $this->initConnection($this->_pdo);
393 $this->_active=true;
394 }
395 catch(PDOException $e)

Looks like your config is not correct, still.

You can move config.php to your home folder and redo the installation steps.

I'm beginning to think a reinstall might almost be easier (I can still download a backup of everything, is that advisable?).

There's no difference between moving config.php and a reinstall.
Yes, do a backup first.

I like to reinstall from new directly , using same DB .

It's more clear and work great .
