 * Warning: inet_pton() [function.inet-pton]: Unrecognized address 2620:0:1c00::
   in ………..\wp-content\plugins\wordfence\lib\wfUtils.php on line 229
 * Wordfence has begun giving the above “unrecognized address” error messages, and
   appears not to be functioning. The same error appears two or three times at the
   top of each page I try to load. The line referenced concerns IPV6 support. Any
   ideas on how to correct this, without being able to update the server’s installation
   of Apache?

 * Hi,
 * Try removing Wordfence and all table data and then do a clean reinstall. That
   should take care of it.

 * Thanks for the tip, though it made no difference. I’m still getting the same 
   unrecognized address errors after following the solution above.
 * I seem to recall reading somewhere that it may be related to the version of Apache
   that is running on the server, and its compatibility with IPV6. But at the time
   I read that I wasn’t having any problem.

 * Hi,
 * Since reinstalling didn’t help, you will probably need the host to update PHP
   to solve the problem. If the addresses are appearing in Wordfence, you are getting
   IPv6 traffic and Apache is accepting it, so the host should use a version of 
   PHP that supports it.
 * One caveat — if you use CloudFlare, they have an option that allows IPv6 traffic
   even if your host doesn’t support it. In that case, you may just need to turn
   off the IPv6 features in your CloudFlare account.
 * If the messages appear at the top of every page, you might also need to turn 
   off WP_DEBUG in your wp-config.php. WP_DEBUG could leak information that attackers
   can use, if it’s enabled on a live site. (If you disable it, you can still find
   error messages in the site’s “error log” file, if needed.)

 * Thanks for the tip on turning off WP_DEBUG. I disabled wordfence to stop the 
   errors from appearing. Now to see about getting the host to update PHP. Cheers
