Liferay无法通过代码或控制面板删除任何内容

我想我可能不小心改变了我的生活，雷。现在我无法通过代码和控制面板删除任何内容。我可以查看和编辑站点/用户/组织，但当我尝试删除它时，在控制台和控制面板中会出现NullPointerException，用户和组织Portlet不会呈现

这是给用户的

你能粘贴异常吗？添加了用户删除的异常不确定这是否有帮助，但至少尝试重新索引所有内容服务器管理->重新索引。似乎您的liferay是如何损坏liferay db的。您可以尝试以下两个步骤1进行db备份2在新的db中设置liferay 3还原自定义表4，除非强制要求，尝试还原liferay表最有可能的是，您会在其中找到罪魁祸首。我可能意外更改了某些内容：您是否手动/通过sql在数据库中写入/更新/删除了某些内容，或者您认为这些更改是如何生效的？
