I've been having very strange problems when attempting to access two of my domains (both WordPress sites hosted by Hostgator).
With one domain, I can log in to the WordPress admin panel but problems happen once I do. For example, I just wrote a new post in WordPress and when I hit the "preview" button, it returns a 404 error. I got the same 404 error when I attempted to save the draft. There are other small issues, like an image I added to the post is not showing up even though the link is correct.
With the other domain, I can't even login to the WP admin panel. I get a 404 error.
But here's the strangest thing about it: all of these problems only happen with Safari! If I use Firefox or Chrome I don't experience any of the issues.
I tried clearing the internet cache with Cocktail (Mac OS X), and emptying Safari's cache and clearing cookies. No effect.
I've never even heard of something like this. Any ideas?
