Long posts disappear. Bug?

How long a post are we talking about? (there’s a word-count on the edit post page).

A bit more than 804 words.

Is the data there if you view the page source?

No. Data is also absent. But the title and the commants are on their places.
I made 866 words and it disappeared. I can give you a link where you can see it. May be it will be more evident than my explanation. Here it is: https://www.droidnews.ru/obzor-kommunikatora-htc-tatoo

Can you, please, say when you visit the link and it is no more needed?I’ll correct the post then to 804 words again.

I see what you mean.

Have you tried splitting up the posts by pages? You can put <!--nextpage--> in to split them up within the same post.

Thanks! <!-- nextpage --> works fine. I’ll use it then.
