CURLPROTO_FILE problem

I am sorry for this meesage. I have problem about Aggregatio module. But Agregation module issues last message at 6 weeks ago.

I have this message:

warning: curl_setopt() [function.curl-setopt]: CURLPROTO_FILE cannot be activated when in safe_mode or an open_basedir is set in /home/xxxxxx/domains/xxxxxx.com/public_html/modules/aggregation/aggregation.module on line 1219.

What is solution?

Thanks.
