java无法将Liferay页面发布到远程Live Box

Question

我在Liferay 7.1中有一个作者（1个数据库）和远程实时（1个数据库）设置

我一个接一个地将所有公共页面发布到远程live Box，这是成功的。突然，我开始出现以下错误

 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].

在这个错误之后，我无法发布任何页面，我不断地遇到同样的错误

如果有人能指导我如何解决这个问题，那将非常有帮助。我真的在努力克服这个错误

附上了截图。
