[eluser]rochellecanale[/eluser]
hello guys just wanna ask how can i run my codeigniter project in CentOS server? Im using a linux OS. I putted all my codeigniter code(folder) in var/www/html directory but when i try to access it it displays nothing. I try accessing my code using this URL http://122.52.126.238/eMLM. I also configured the config.php replacing the baseurl with the new url. $config['base_url']= 'http://122.52.126.238/eMLM/';
Please help me guys what should i do? One thing, when i try to create a simple html and php file it shows in the browser. But why my CI code wont run? What should i need to configure? Please help me. Im running out of time.
