Not sure where to begin on the issue, basically a few months back i had a perfectly running website, etc sql all intact, but since it got closed down ive tried re-uploading it to a dns hosted via Xampp, re-uploaded the webpages and the sql database but its as if the php isnt connecting to the right database and im not sure how to go about fixing this? its all uploaded fine showing the tables but the php webpages are acting as if its being directed elsewhere.
