I use wordpress 3.5.
From the time that I updated the plugin to 2.82, the following message appears in the wp useronline page:
Warning: gethostbyaddr() [function.gethostbyaddr]: Address is not in a.b.c.d form in C:\inetpub\wwwroot\wp-content\plugins\wp-useronline\template-tags.php on line 240
and the ip that is shown to the user is like: fe80::8489:a6d8:2d89:4f97%11
Do you know how to fix this problem?
Thank you in advance
