I purchased a very well-known 3rd-party php-based forum software. Uploaded to my server, run it for few weeks. This morning, when I visit my site, it display all the PHP code, including all the comments etc, like what you will see if you open it with notepad. It was very scary, my database config which is in PHP file also visible, what happened? I have no choice but to take my website down now.
What should I do? How can view PHP code? I thought PHP code is very safe?
Has somebody hacked my website?
