my post can not be found

Hi,
I have published a post and after a while my post can not be found: I can find it through search, but can not open full text. If I login as an admin I can see the whole text, can edit it, but even an update does not allow me to see the whole text. Nearby posts are fine.

The invisible post has a piece of code copied from vimeo.com that plays video; full link to video – https://vimeo.com/21479800. It used to work just fine when it was published. Original video is in place. I tried replacing my code with the newly copied from vimeo – did not help.

Deleting the “video” code – does not help. I believe video has nothing to do with the trouble.

Invisible part of post is still searchable – I can find this post by a word which I can’t see.

Link to my post, if it helps – https://greenq.ca/news/index.php/2011/85/

Any suggestions are very welcome.
