I just making my new website and I installed add-ons in the package, but when I go back to my previous website home, I've got the message,

An unexpected error occurred.

Argument 1 passed to Concrete\Core\Express\Form\AbstractRenderer::__construct() must implement interface Concrete\Core\Express\Form\FormInterface, null given


What should I do?

First, I just editing my website, then I went to add-on and installing some free add-ons. I just installed about 6 free add-ons for layout, live chat, blocks, tec. But, when I want to checked my website to began editing again, the error occured.

That just what I've done before I got the error.

And today, when I login in my concrete5 account, and after login, when I see my website again, I was been told to login again.

I would like to say thank you for your response.
