404 email alerts gone MAD!

Support

1

Hi,
I set up 404 alerts in the maintenance extension to be alerted when a visitor lands on a none existing page but myself and some of my clients are getting bombarded with 404 alert emails now and I can’t stop them!!
I wasn’t expecting the amounts of alerts I am getting.

I don’t seem to be able to turn off the alerts now. I click the ‘Enable 404 email notifications’ off, save the settings the extension syncs with my child sites and the ‘Enable 404 email notifications’ toggle is still green (on)

Please help

Thank you.

Regards

Richard Thorne

Hi @RichThorne

Can you please check your Error Logs and paste your results here? This can be found at MainWP > Info > Error Log.

And also, can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server, on the top right of the page.

Be sure to use the button like the one below; this button hides all your private information:

Pressing the button auto-copies the report to your clipboard, then just paste it in a reply here.

If hackers are trying to test for installed plugins (vulnerabilities), backdoors, webshells etc. you will get a lot of 404s (hopefully :wink: ), so I’m not sure why you even want to enable there alerts.

Cos I didn’t understand the impact of activating the alerts.

I think the alerts have stopped now, although the 404 alert screen still shows as if it’s activated.
Here’s the error log (last 49 results)…

Thank you for the system report.

Would you mind opening a private Help Desk ticket so we can collect some additional information & investigate further?

Just to provide an update on this - there was an issue with deactivating the 404 alert option on several sites so the full uninstall and reinstall of the MainWP Child plugin was necessary.
