Go into your php folder, search for the php.ini and search in there for short_open_tags and put there an On.
That should solve it.
If you got some more errors still just put a error_reporting(0); at the top of your index.php (within the php tags ofc)
So you got:
<?php
error_reporting(0);
...
Important: usually that's not what you should do, because the error reporting forces you to write better code
also, only do this if the php part works fine for you!
