I’m using Worfence for a long time and didn’t have any problems until now.
It looks like an update occured some days ago, making my error.log file spammed of these errors:
PHP Fatal error: Call to a member function get() on null in PATH/wp-includes/query.php on line 28, referer: WHATEVER LINK THEY VISIT [:error] [pid 18983] [client BLOCKED_IP] PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0, referer: WHATEVER LINK THEY VISIT
I can tell it comes from Wordfence because only the blocked IPs (from advanced blocking, didn’t check for the normal blocking) are triggering this message. Also, and it may be related, the last WF scan failed. I canceled it but I still get a ton of those messages.
Please help me fix this As soon as possible.
EDIT: blocked myself to test, and the blocked users get a “Error couldn’t display the page HTTP 503”
