hi.

 

on checkout (address) both delivery address box and invoice box are empty (in console I have Uncaught TypeError: items[field_item].replace is not a function). 

 

line from quick-order: items[field_item] = items[field_item].replace(",", "");

 

i have virus on my site and my server administrator disabled function on server but i dont know is something is necessary to presta work properly: show_source,shell_exec,passthru,exec,proc_open,parse_init_file,curl_multi_exec,passthru, php_uname, phpAds_remoteInfo, phpAds_XmlRpc, phpAds_xmlrpcDecode, phpAds_xmlrpcEncode, popen, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, posix_setuid, posix_uname, proc_close, proc_get_status, proc_nice, proc_open, proc_terminate, shell_exec, syslog, xmlrpc_entity_decode,system
