Caching 自1月1日起随机发生奇怪的umbraco媒体缓存错误

我们正在运行umbraco 7.15.1

突然，我们的徽标文件出现缓存错误，这是随机发生的。一开始它就导致我们所有的网站瘫痪

尽管它是网站的主要形象-标志-但它只发生在随机选择的地方。例如，徽标在网站标题上显示良好，但在电子邮件模板或模式片段中失败

当它第一次发生时，我们确实更新了服务器上的dll，问题似乎已经解决了，但昨天它突然再次发生——在一个完全不同的地方——在本例中的预定任务中

有人知道为什么会发生这种情况，或者如何永久性地阻止它再次发生吗

这是相关stacktrace的示例：

是Logo属性的

get

访问器

该属性位于我们的umbraco中的

设置

文档类型下。其名称空间是MySite.PublishedModels。标志是媒体纠察类型

---

由于某些原因，它根本无法获取徽标媒体文件。

关于get_Logo（），您有什么建议？你为什么需要一个方法来实现这一点呢？

get_Logo（）

是

get

访问

Logo

属性的方法-请参见上面的@MarioMaybe我的更新，因为它与遗留选择器有关？您可以尝试替换Umbraco.MediaPicker2的选择器的属性编辑器。
