Thread:Help talk:Extension:Translate/Update untranslatable content in translated pages/reply (3)

http://tangowiki.org/wiki/Lyrics:Adoraci%C3%B3n was removed from translation and is not listed at all on http://tangowiki.org/wiki/Special:PageTranslation

It's not corrupted, you simply have to edit it (e.g. change a space) so that Translate "sees" it again. Then you can mark for translation, I think.

As for other pages, I'm not sure why an edit like would corrupt the page, but it may be something very simple. Try adding a newline after a closing translate tag or before an opening one and see if it changes something.
