404 error since updating to version 5.161.1

Hello, @dmjarvis.

Please, re-activate the plugin:
? WordPress Admin Page —> Plugins —> Installed plugins —> Anti-Spam by CleanTalk —> Deactivate and Activate again

It should fix the issue. Did it help you?

Hi Serge.
I’ve tried that, then cleared cache and even re-saved the permalinks, but I’m still seeing the 404s (52 of them in the 1 hour since I reactivated the plugin).
