Hi,

After upgrading to EPiServer CMS 6 R2 and Composer 4 R2 we're experiencing problems when pasting copied pages.

• Sometimes an error occurs right away when pasting the page.
• Sometimes the page is pasted but the tree won't display the page until it's refreshed manually.
• All the time the status text telling the user a background job is in progress fails ("1 jobb misslyckades. Visa information.").

If it helps we think the following log text might be related to the above described:

I've read in a blog post about issues with Composer 4 R2 and PageType Builder, but as far as I know we haven't installed the latter.

Any help is greatly appreciated!
