Getting php errors reported when Admin Tools blocks a WordPress bot probing attack.

Reference the stack trace email results below...

Admin Tools’ DFI Shield (DFIShield::onAfterRoute) flagged the request and called blockRequest().

While logging the block, escapeLogLine() got null where it requires a string, so PHP 8 threw a TypeError. The likely cause is one of the spoofed or empty values (probably something in the header data) coming through as null.

So the plugin’s bug is real, but the bot triggered it. The block itself was working as intended. The side effects are that the request wasn’t logged properly and I got an error email.

A PHP Exception occurred on your site. Here you can find the stack trace:
