Unable to resolve class

[Dawid Górny]

Recently my company has updated our confluence version to 7.13 and as far as i know some of the classes has been changed or removed.

This causes problem:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script433.groovy: 7: unable to resolve class com.atlassian.confluence.pages.Page
@ line 7, column 1.
import com.atlassian.confluence.pages.Page
^

I cannot find any replecement for this class, is there maybe a page that shows updated versions of classes?

Aslo i would be greatfull for quick fix idea
