Major bug fixed in CMS10 and TinyMce1

We have just published quite an important bugfix that affects everyone still using CMS based on tinymce3 so:

  • All EPiServer.CMS.UI10 packages that had tinymce bundled
  • EPiServer.CMS.UI11 + EPiServer.CMS.UI.TinyMce 1.0.0 or EPiServer.CMS.UI.TinyMce 1.1.0

The issue was very annoying to the editors because it affects all context changes (changing the page in the tree, navigating to a block etc.)

More info available here:

https://world.episerver.com/documentation/Release-Notes/ReleaseNote/?releaseNoteId=CMS-14712

If you are still on CMS10 or use TinyMce1 please install the appropriate hotfix or preferrably upgrade to the most recent version.
