Error editing Publishing setup

Getting this error message when trying to edit a Publishing setup:

Object of class [com.percussion.services.sitemgr.data.PSSite] with identifier [461]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.percussion.services.sitemgr.data.PSSite#461]

What does it mean?

Also everything stopped publishing, pages, assets etc…

Hi Conan -

By chance had you or someone else recently started copying a site? We’ve seen this issue once or twice, and it appeared to be related to copying a site.

Refreshing your browser may resolve the issue for you.

Thanks,

Hi Conan,
