I recieved an error after updating on the backend.It says:

Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in /usr/share/nginx/html/landing-page/todo/php/todo.php:29 Stack trace: #0 /usr/share/nginx/html/landing-page/todo/php/todo.php(29): PDO->__construct('sqlite:../db.sq...' #1 {main} thrown in /usr/share/nginx/html/landing-page/todo/php/todo.php on line 29

And some functions doesnt work properly,for example it shows 5 Notifications but in fact there isn't any notification.And It doesn't disappear,I can't open Notification it just loading...Who can help me how to fix that bugs?

@Hacky snap

@hard_as_snails U got the similar problem?

You can ignore that error.

As for notifications, we have made it similar to facebook notifications, that is the notifications stay as they are until clicked and are marked as read/unread.

We may have to remove that number so that users are not confused.
