I have kind of a weird problem. Whenever I publish a post on my site, it doesn't publish right away. After I publish a post, it just sits there for like 20 seconds, then it asks me if I want to open "post.php". I click cancel. During this, if you try to go to the public homepage of my site, nothing comes up (just a blank site). Then, after about 3 minutes, the site comes back up, and the post is published. This happened in 2.3, and is still happening in 2.5.
Hopefully I've accurately described whats happening. Does anyone know my problem?
