Thanks for quick reply. I’ve already went through all files and can’t find any reason. In functions.php there is no function which overrides or stripes or filters the content. I’m using only standard wp functions and tags (all with Codex in my hands). Could You please point me where to look? What can make <!–nextpage–> tag unrecognizable? I’ve also switched to Twentyeleven theme and there is exactly the same problem.
