I'm new to this, but I had a previous attempt at setting up WordPress on my hosting provder server. It worked OK but at the time I went off and forgot about it.
Returning to it I found I had created three pages and half a dozen posts. It all worked OK except that when I went to http://www.mysite.com/wordpress/ I always got one of the pages, not any of the posts. They were available in the side menu listed under recent posts, categories etc. All those links worked. I then deleted the three pages thinking that would start my posts appearing but it doesn't. In the WordPress default theme, I get the correct header and footer, and the side panel and its links all work but the main content area displays 404 file not found. In some other themes it says 'Sorry there were no posts to match your criteria' as if I'd put in a search.
Can anyone advise me how to fix this without clearing the database and reinstalling from scratch? (I'm willing to do this but I expect there's an easiesr way.)
