Just a basic question, I had worked on a site, and everything was fine, the next day it was giving problems, when I checked all my php tags were converted to php shortcode tags, and to top it off some BASE variables had changed. Could the server had done this, or would it be someone else who tampered with it?
I doubt that the server changed ur code given the extent of the changes. I would look at the code again to make sure no other code was inserted in there.
What do you mean by “shortcodes”? Are you using WordPress? The site could have been hacked if you
did not have good security on it. Perhaps you could give us more info such as show a section of your
“shortcodes” and more info on what has changed.
