Sorry to say, if you are self hosting a tool like Zenphoto or any other you need to learn about basic stuff like error logs.
zenphoto.4allindians.com/zen/setup.php That will not work. zenphoto.4allindians.com/zp-core/setup.php is the link to run setup. Which actually would happen automatically.
btw do latest zenphoto version encounter any problem in "search " function
Not that we know of naturally.
