Can't update pages after upgrading 2.x to 3.x

[siam02]

I have recently upgraded from Twill CMS 2.X to 3.X. Everything works well except updating or publishing posts. I am getting this error:

{message: 'Page', exception: 'A17\\Twill\\Exceptions\\NoCapsuleFoundException', file: 'G:\\fileion.com\\vendor\\area17\\twill\\src\\TwillCapsules.php', line: 83, trace: Array(65)}

How can I fix it? Please help.
