After PHP upgrade: Piwik config is misconfigured. Either remove confit.ini.php or resume install



I recently upraded my PHP version to 5.3.27, and now when I try to log into my Piwik, I get the following message:


Your Piwik configuration file appears to be misconfigured. You can either remove config/config.ini.php and resume installation, or correct the database connection settings.

The PDO extension is required for this adapter but the extension is not loaded

I noticed this message from Matt in another thread:

I created a new db user and password, and added it to the config.ini.php file, but that did nothing.

Other than downgrading PHP to the previous version, what can I do to get my install back online?

Thanks in advance,

please ask your web host to enable PDO on your server for your PHP version


Hi Matt,

Thank you for your quick response. I checked my php.ini file to see if it was enabled, and PDO was enabled. I reverted my php.ini to the default, and that fixed the issue.

Thank you for your help,
