RW classic vs RW8

I created a website last year with RW8.
I have upgraded to RW classic, but with classic a lot of features are now missing on the different pages.

No features were removed! I’m wondering if you’re missing some third-party addons in Classic…

With RW8 I only used your app. I don’t believe that I have any add-ons.
The different pages for the website are still all there, with the key text and most of the pictures still there.
The background etc, for the pages have changed, and some pictures are missing,

Also, I still have RW8, but it will no longer open the site the same way that it was created. That is why I updated to classic, hoping that it would be better.
Do I have to rebuild the entire site?

Can you share your project with me? You can send it to support@realmacsoftware.com - let me know once it’s been sent so I can keep an eye out for it in the support system.
