这是我从 Plone 4.2.1 安装(在 SuSE Linux 上)的回溯:
Traceback (innermost last):
Module ZPublisher.Publish, line 126, in publish
Module ZPublisher.mapply, line 77, in mapply
Module ZPublisher.Publish, line 46, in call_object

Module ZODB.Connection, line 587, in _commit
Module ZODB.ExportImport, line 176, in _importDuringCommit
AttributeError: 'module' object has no attribute 'NavigationViewlet'
奇怪的是,我不明白的是,为什么只有一个 Plone Site 在导入比 Plone 4.1.5 更新的实例时显示此错误?
Plone 站点仅安装了以下附加插件/产品(与其他插件一样,但它们都可以正常工作):
- LinguaPlone
- PloneFormGen
- 产品.ZSyncer
- 集体快速上传
那么,我的错误/错误在哪里?
感谢您的帮助,因为该站点现在太大了,无法从头开始在新的 Plone 实例中“重建”它:-(
