Since the page http://translatewiki.net/wiki/Support has been altered from a normal talk page, it still has an "edit" link on its top, but that does not lead to the wiki code of the ciomplete page content any more, and editing the page as a whole is not working any more.
Yes, you cannot edit the page as a whole anymore. That is expected behaviour.
This is awfully counterproductive if you need to make systematic changes or additions, or you need to find specific wikitext.
Implementing whole-page wikitext editing is not justified by its benefits (and would be a hacked interface – the page is generated dynamically). You should use the far more intuitive and useful interface that already exists. If you do not like this, you should not use LiquidThreads.
