My b2evolution Version: Not Entered

Dear ,
now , we have problem with :
PHP allow_url_fopen
On

When enabled, this feature is known to facilitate hacking exploits in any PHP application.

b2evolution includes additional measures in order not to be affected by this. However, for maximum security, we still recommend disabling this PHP feature.

If possible, change this setting to allow_url_fopen = Off in your php.ini or ask your hosting provider about it.
PHP Magic Quotes
On (magic_quotes_gpc)
PHP is adding extra quotes to all inputs. This leads to unnecessary extra processing.

If possible, change this setting to magic_quotes_gpc = Off in your php.ini or ask your hosting provider about it.

Plz help me how to modif this web hosting.

Thanks
