I've got the following weird problem:
If I write short posts, they are published fine. However, if the post is a little bit longer (say 30 lines) and publish it, only its title is shown in the main loop. The entry text misteriously disappears. As far as I understand there should no limit for the post number of characters! I'm dealing with an already installed wordpress. With thos e I've installed myself I've never found such a problem.
Today I've also noticed that although when a post is 'short' enough to be shown, if too many comments are posted (say 4) the post text also disappears. It is as if the global (post text + comments) reaches some 'invisible' limit.
I use Firefox and WP 2.1.3 in Spanish.
