PHP.INI settings: Disable function curl
	
	
		Open a terminal or login to your server over the ssh session. Open php.ini file:
Find disable_functions and set new list as follows:
	Mã:
	
disable_functions = exec,passthru,shell_exec,system,proc_open,popen,parse_ini_file,show_source,curl_exec,curl_multi_exec
 I also recommend to disable allow_url_include and allow_url_fopen for security reasons:
	Mã:
	
allow_url_fopen=Off
allow_url_include=Off
 
Save and close the file:
	Mã:
	
# service httpd restart
