I just copied ojs 2.4.8.4 on my website home director. I am trying to install old version since my webserver provided old php version (4.8). I tried to bring the installation screen. However, at this point browser only returns a blank screen. All file permissions are checked and no problem there, tried other options as well, but the screen remains blank and installation screen do not turns up. The same thing working very perfectly with local server settings. If someone have any idea, please inform. Regards
