I don’t think you have php on that server you’re on… or you messed up the install.php file somehow..
well, i havent done anything to the file itself other then upload it, and the host im using says it allows .php files
make a file that has <?php phpinfo(); ?> and save it as a .php file. then see if it shows something or the other. If it shows gibberish then you don’t have php working otherwise it’ll show something like this
I still think you don’t have php working cause it shows <?php e_(‘Continue to the Second Step’) ?> which is impossible when you have php installed as php code can’t be seen client side.
