问题
Iam having a Author(with 1 database) and Remote Live(with 1 database) setup in Liferay 7.1.
I was publishing all public pages one by one to remote live boxes which was successful. suddenly I started getting the below error,
The publication process did not start due to validation errors.
The model.resource.com.liferay.site.model.adapter.StagedGroup
<?xml version='1.0' encoding='UTF-8'?><root available-locales="en_US"
default-locale="en_US"><Name language-id="en_US">Guest</Name></root> could
not be imported because of the following error:
org.hibernate.StaleObjectStateException: Row was updated or deleted by
another transaction (or unsaved-value mapping was incorrect):
[com.liferay.portal.model.impl.LayoutImpl#296619].
After this error I couldn't publish any pages, Iam keep on getting the same error.
If anyone can guide me on how to solve the issue it will be greatly helpful. Iam really struggling with this error.
Attached screenshot as well.
