I see, so you are not using any hosting services that I know of. XD Your friend may have disabled allow_url_fopen for a reason, you need to consult him and ask whether it is possible to enable allow_url_fopen property in php.ini. This is crucial if you want to use bbcode on other sites/forums, otherwise they won't be able to see your images and other uploaded stuff.
There is a chance you may be able to edit your php.ini through cpanel. Do you see a module called 'php configuration'? If so, click it and see if you can do anything about php configuration there. For me, this is not an option and I have to consult my own host to update php settings. XD
If you wanna know what your php.ini setting currently is, create an empty php file and enter this code below:
PHP Code:
<?php
phpinfo();
?>
The page should look like this below:
