Title: Error 404 when checking Last modified: February 11, 2021 --- # Error 404 when checking * [samoreen](https://wordpress.org/support/users/samoreen/) * (@samoreen) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/) * Hi, * Thanks for the useful plugin. * I just tried to check and I got a 404 error : * “The requested document was not found on this server.” * I’m using WP 5.6.1 and Astra Pro. The settings detected by the plugin are as follows :: * SendMail path (UNIX): /usr/sbin/sendmail -t -i SMTP server (Windows): localhost SMTP port (Windows): 25 Add X header: * If this behavior demonstrates that my WP installation is unable to send mail ( which I suspect), I’m OK. But this result is unclear. * Thanks in advance.

Can you please let me know when you got that error? When you check and send a test email such an error should not display as it seems to be related to an existing page/file. Please let me know the steps you took and when did that error display. * Thank you, Mihaela * Thread Starter [samoreen](https://wordpress.org/support/users/samoreen/) * (@samoreen) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14063492) * Hi, * I did nothing special. I just installed the plugin, entered a valid destination address and immediately checked => 404 error. * I just tried again after uninstalling and re-installing. I have now a working SMTP setup (MailGun + WP Mail SMTP). I still get the same error while the email check in WP MAil SMTP is working fine. * So I no longer need Check & Log EMail anyway but I just wanted to report the problem. * Patrick * [steweill](https://wordpress.org/support/users/steweill/) * (@steweill) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14069915) * I have the exact same problem – after I send the test email it goes to my 404 page. * [Miha](https://wordpress.org/support/users/mplusb/) * (@mplusb) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14090506) * Hi guys! * Thank you for explaining! Please rest assured we will help asap, but need to debug a bit more. It may be an incompatibility with another plugin. Could you please install this plugin: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)? After you install and activate the above plugin it has a Troubleshooting mode which allows you to have a vanilla WordPress session, where all plugins are disabled, and a default theme is used, but only for your user – your visitors will still see the normal website. * Go to its troubleshoot mode and activate only this plugin and see if the same issue happens with a default WordPress theme (Twenty Twenty for example) and no other plugins. Please let me know how it goes. Thank you! * Warmly, Mihaela * Thread Starter [samoreen](https://wordpress.org/support/users/samoreen/) * (@samoreen) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14090534) * Hi Mihaela, * > It may be an incompatibility with another plugin * Not sure. I tested the plugin on a local WP installation without any other plugin enabled. Just a fresh WP + Astra theme (free version). I got the same 404 error. * Patrick * [Miha](https://wordpress.org/support/users/mplusb/) * (@mplusb) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14101358) * Thank you so much for explaining! Is it a multisite installation? We will try to debug further and see why this happens. I went ahead and opened a ticket regarding this on our GitHub. We sincerely apologize for the trouble! * Warmly, Mihaela * Thread Starter [samoreen](https://wordpress.org/support/users/samoreen/) * (@samoreen) * [5 years, 3 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14101413) * > > Is it a multisite installation? * No. The problem also occurs on a simple XAMPP installation with no other plugin installed. * Patrick * [erzo123](https://wordpress.org/support/users/erzo123/) * (@erzo123) * [5 years, 2 months ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14297334) * Hello, I just install et activate the extension Check & Log Email I want to test if my server is able to send email. So i use the “Send a test email” form and i indicate my own email. I get an 404 error ! Is there pre requisite before using your extension ? Thanks in advance * [mjayas](https://wordpress.org/support/users/mjayas/) * (@mjayas) * [5 years, 1 month ago](https://wordpress.org/support/topic/error-404-when-checking/#post-14306130) * Ran into same problem. Issue for me seems related to my WordPress installation not being in my server’s root directory. * As a result, the form on the Check & Log Email status page posts to the incorrect location: * `
` * In my case, the `action` attribute should post to `/wordpress/wp-admin/admin. php?page=check-email-status` (or, more simply, `?page=check-email-status`). When I manually correct that using the browser’s dev tools and then click ‘Send test email’, it works fine — no 404. * It looks like (as of my posting this) [line 98 of the plugin file **Check_Email_Status_Page.php**](https://plugins.trac.wordpress.org/browser/check-email/trunk/include/Core/UI/Page/Check_Email_Status_Page.php#L98) hardcodes this absolute URL for the `action` attribute instead of maybe leveraging [`plugin_dir_url()`](https://developer.wordpress.org/reference/functions/plugin_dir_url/)( or even just using the relative URL `?page=check-email-status` as mentioned above). * I think that would resolve this issue, at least in my case. attn: [@mplusb](https://wordpress.org/support/users/mplusb/) - This reply was modified 5 years, 1 month ago by [mjayas](https://wordpress.org/support/users/mjayas/).
