I have a problem with the localization of the LinkManager which is a part of the Sitecore Rich Text Editor.
The LinkManager in Sitecore which can be accessed through the rich text editor does not show any labels anymore.
We upgraded from 6.3 to 6.6. Before the upgrade it had worked fine. The language we are using in the backend is german.
The folder sitecore\shell\Controls\Rich Text Editor\Localization\ exists and there are german localization files as well.
Does someone has an idea how to fix this issue?
