When using the links button in the editor SilverStripe uses [sitetree_link,id=66] in the href to identify the page. When viewing the site, Silverstripe then changes these to be the actual page name.
With the Subsites module installed these are no longer working, Silverstripe is no longer converting the [sitetree_link] to the page name. Which causes page not found to show
Also other plugins installed are Userforms and Multi language
Any help would be greatly appreciated
