Answer 1

这是影响AEM 6.0,6.1和6.2的已知产品错误。

来自official documentation

这是一个已知的产品bug CQ-4215298。当用户创建版本或发布（“激活”）由另一个用户锁定的页面时，它会导致页面进入不一致状态。

解析度

AEM6.3和AEM6.2 SP1累积修订包8中已修复此问题。

无论是否应用修订包，您都必须修复损坏的页面。要修复页面，请按照以下步骤操作：

转至/crx/explorer/index.jsp并以管理员用户身份登录。打开Content Explorer。浏览到损坏页面的jcr：content子节点。例如：/ content / geometrixx / en / services / jcr：content转到Versions => CheckOut。转到/sites.html UI并浏览到该页面并将其打开以进行编辑。单击左上角的锁定图标即可解锁页面。
