Config problem after instalation...

[legendofmir]

I instaled vBet 4.0.0 on my forum and in language EN , work just fine but in all others language say to me:

Fatal error: Call to undefined function curl_init() in ....\forum\includes\vbenterprisetranslator_functions.php on line 647

I think must to setup this product somewere, but i didnt understand what to do, reading this in readme.html from do_not_upload:

Some steps are marked as (ONLY for utf-8 charactersets) or as (Required for NOT utf-8 charactersets) - it means that you will made this steps according to yours forum characterset (how to check my forum characterset).

(Required) Set "Meta Description" - even if you use some mod which changes meta description for threads, please set some value here - otherwise RSS can be broken.
(Required) Set "Enforce Canonical URL" to 'Strict' - otherwise vBuletinTM can break some characters taking more than 1 byte (i.e. from Japanese).
(Required for NOT utf-8 charactersets) Set "Number of Characters Before Wrapping Text" to '0' - otherwise vBuletinTM can break some characters taking more than 1 byte (i.e. from Japanese).
(Required for NOT utf-8 charactersets) Clear "Blank Character Stripper" value - otherwise vBuletinTM can break some Japanese signs (those signs are part of Japanese signs)

Where to set this... more easy help are for this coz in my LanguageManager dont appear:

Meta Description

only English and EDIT/Translate....

Must to add all the language in there, manualy?

What to do, to work and for the others language, like greek, romanian,...more?

At 647 line are this in vbenterprisetranslator_functions.php:

$connection = curl_init(); 

PS: No vBSEO instaled, only forum and few products... with my host(dedicate)
