Moving CI website to another server - only blank page showing

On thing you could check is if you have used short PHP opening tag (<? instead of <?php) anywhere in your code, and if you have, make sure your new server has short_open_tag=On in php.ini

Alternatively you can make sure all your code uses <?php or <?= and no short tags.

That little thing got me quite few times.

I set the short_open_tag to On, but nothing happened :/
