This weekend, started from Friday 21th,

Now, it looks like the site was being SQL Injection, the hacker changed admin email, using forgot password option, then change the Forum Closed Message.
But it has more problem that just that, right now, the site is still being abuse and spam by and being DOS attack, The hacker somehow able to put malicious files on the server. It seems to me they been exploited PhotoBlog upload options to upload files
Edit: Security bug found.
