Undefined index

Same here: “Notice: Undefined index: coreUnknown in wp-content/plugins/wordfence/lib/wordfenceHash.php on line 141 0”

All I know is now all the bots found my site and are banging like crazy… ??

I have the same message from my WordFence plugin.
Undefined index: coreUnknown (8) File: /home/Admin/public_html/wp-content/plugins/wordfence/lib/wordfenceHash.php Line: 141
Notice: Undefined index: coreUnknown in /home/Admin/public_html/wp-content/plugins/wordfence/lib/wordfenceHash.php on line 141
Should I do something?

Me, too. Glad to know I’m not alone. Also experiencing tons of bots!
Notice: Undefined index: coreUnknown in /homepages/40/d642207570/htdocs/wordpress/wp-content/plugins/wordfence/lib/wordfenceHash.php on line 141 0

Thank you very much! All right, after updating the plugin. There are no more errors.

“Also experiencing tons of bots!”

That didn’t have anything to do with that error…

Same here … I noticed that the failure came after the update to 6.1.14 update on my websites…

Tried to deactivate the module after exporting token with settings, and delete all tables and data in db for WF, and then deleted the module from the system . Reinstalled and exported the former settings..and it worked ..no problems with the err msg anymore…. Did the same on 3 sites and all is good now… dont know if it was just a lucky incident, but it surely worked for me ??

Updated wordpress today to latest and sponsors plugin and now getting these notices:

on widget section:

Notice: Undefined index: order_by in /hermes/bosnaweb04a/b2516/nf.sexualassaultroadsho/public_html/wp-content/plugins/wp-sponsors/includes/class-wp-sponsors-widget.php on line 24 Notice: Undefined index: max in /hermes/bosnaweb04a/b2516/nf.sexualassaultroadsho/public_html/wp-content/plugins/wp-sponsors/includes/class-wp-sponsors-widget.php on line 37

and on page that I have sponsors:

Notice: Undefined index: orderby in /hermes/bosnaweb04a/b2516/nf.sexualassaultroadsho/public_html/wp-content/plugins/wp-sponsors/includes/class-wp-sponsors-shortcode.php on line 29 Notice: Undefined index: max in /hermes/bosnaweb04a/b2516/nf.sexualassaultroadsho/public_html/wp-content/plugins/wp-sponsors/includes/class-wp-sponsors-shortcode.php on line 30

Wordfence can show an “Undefined index” problem in a plugin when there is actually a bug (the developer may call it an “unimportant, tiny oversight”). For instance, one of my custom registration plugins failed to test the POST vars for values before adding to the administrator’s new user notice (for shame!), and Wordfence gave me the dreaded “Undefined index” issue because the $POST[‘var’] was undefined.

This is not a bug in Wordfence! It shows a bug in the indicated plugin file.
