Error after upgrading to 3.17.0

[pascal]

I got this randomly:

Fatal error: Uncaught Error: Class 'PDO' not found in /home/mywillys/public_html/lib/G/classes/class.db.php:71 Stack trace: #0 /home/mywillys/public_html/lib/G/classes/class.db.php(110): G\DB->__construct() #1 /home/mywillys/public_html/app/loader.php(66): G\DB::getInstance() #2 /home/mywillys/public_html/index.php(20): include_once('/home/mywillys/...') #3 {main} thrown in /home/mywillys/public_html/lib/G/classes/class.db.php on line 71

Also, look like I'm not able to save new settings under image upload? I hit save and nothing happen.

Any idea?

And I cannot save this also....
