Have you updated anything recently or changed any settings? Added any plugins?
it actually has been occurring since i moved my website to a different host.
Ok. So three things to think about to start.
1) Make sure that all of your files have been transferred properly.
2) Make sure that the URLs in Setting->General point to the right place. This is especially important if you’ve transferred a DB, which it seems like you have.
3) Make sure that your .htaccess is correct for the new host and doesn’t contain anything peculiar to the old host. This is important if you are using permalinks. You could just rename your .htaccess and then reset your permalinks. WP will write the new htaccess for you if it can or tell you exactly what to put in the file if it can’t.
My bet would be on #1 being the problem. Something didn’t get transferred correctly.
I tired all 3 of them, but problem still exists. I just realized that post is actually published, but instead of leaving in admin panel, it goes to page not found.
If I replace all the files with fresh copy, everything would be stay the same right?
I’m not sure what you mean. Your posts and categories ans such should stay the same. Hopefully ‘everything’ would not stay the same since right now your site is broken.
