Ok, i have updated the php to 5.4.45 when your first said too and I have also create a php info file: https://memoryandmotion.org/info.php
It says memory is 512.
I also added this to info.php like what was in the instructions and this is what my file looks like
<?php
phpinfo();
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)
?>
