ERROR: An error was encountered while trying to authenticate. Please try again.

Hey @carlgross,

Can you please try disabling Two-Factor and reCAPTCHA to see if it helps?

If it does help, it sounds like there might be a conflict either with the theme or one of the plugins you’re using, could you try temporarily switching to a default theme if you’re not already using one and disabling all other plugins then reactivating them one by one to see if the issue persists?

Please let me know what you find.

Thanks,

Gerroald

Hi @wfgerald,

Thanks for the reply. Here are my follow-ups.

>> Can you please try disabling Two-Factor and reCAPTCHA to see if it helps?

reCAPTCHA has is already disabled (screenshot). 2FA was enabled. When I opened the login security page, there was a big blue ‘DEACTIVATE’ button for 2FA. I clicked it, but encountered an error (screenshot). Now, when I open Dashboard–>Wordfence–>Login Security–>Two-Factor Authentication, there is no ‘DEACTIVATE’ button–2FA seems to be enabled for my user (screenshot). If I open the ‘Settings’ tab, 2FA is enabled for admins, and I cannot untick it (screenshot). Thoughts on all that?

One thing I *can* say is that on the all admin pages (including the Wordfence admin pages), there are errors in the JavaScript console (screenshot).

I would love to try these. But as mentioned, this is my live site. Bringing it down to test these is very undesirable. Unfortunately the issue does not occur on my dev site ??

Update: As I mentioned, there are JS console errors in the plugins admin page. Just as a test, I deactivated two of the plugins responsible for these errors. In doing so, I was able to remove both the uncaught (in promise) error and the 404 error. But that did not resolve the Wordfence login issue. So I’m not sure these JS console errors are related. Plus, on the WordPress *login* page, there are no JS console errors.

Hi guys. Any update on this? It’s getting a bit critical on my end unfortunately :-/

Issue resolved. I should first say that in addition to this Wordfence login error, there were many other small non-Wordfence errors across my site, e.g. non-descript error whenever I uploaded an image, could not search for new plugins, etc. It seemed to be related to some commented code in my child theme’s functions.php. When I deleted that code, all of those issues magically went away. I unfortunately didn’t save that commented code for analysis. But I *can* say that it included a <script> tag, e.g.

$test = 'hello world';
echo $test;
?>
<script>
  .body {
    color; red;
  }
</script>
<?php
$value = 10;
echo $value;

My educated guess is that the <script> tag didn’t get commented out in full, or something. But we’ll have to leave it there.

We can consider this resolved.

Similar problem here. The thread is assigned resolved but still I am not sure how to fix it.

I’d suggest creating a new post in these forums with your issue. I say that because:

1. When you reply to a post that has already been ‘resolved,’ the moderators sometimes don’t see those (or possible don’t receive a notification).

2. Your issue appears to be a slightly different issue than the issue indicated in this post. Yours has a specific JavaScript console error associated with it, while the issue in this post does not.

Yes, thanks, I have already realise that I have created a new thread.
