Undefined index: HTTP_REFERER in DbCache_WpdbInjection_QueryCaching.php
-
Hello,
In addition to W3C, I just installed WordFence as I was having the server crash due to bruteforce attacks on wp-login and xmlrcp.php. During a scan with WordFence, this came up:
[Nov 01 03:02:56] Notice: Undefined index: HTTP_REFERER in /home/domain/public_html/wp-content/plugins/w3-total-cache/DbCache_WpdbInjection_QueryCaching.php on line 366 Notice: Undefined index: HTTP_REFERER in /home/easWhat’s the best way to resolve this?
Thanks.

Hello, I’ve the same problem with Wordfence + W3-Total-Cache.
Actually it happens even if you don’t use the plugin panel on a browser.
In fact I’ve my log gets full in background.The fix Simone proposes does not fix my issue. I guess it is limited to check ajax requests.
Anyway It gave me the chance to give a look into the w3c-fix fork ??
Thanks
Same problem here, fixed with @nigrosimone solution.
