wp_mail() 3.6.1 not working

Nothing was changed in relation to wp_mail() in 3.6.1.

Do you check the return value from wp_mail()?

Also, you turn on debugging by adding these lines to wp-config.php:

@ini_set('display_errors',0);
define( 'WP_DEBUG', true );

As @esmi stated, nothing has changed with wp_mail() in WordPress 3.6.1.

Anything in 3.6 then? It could simply be coincidence and perhaps something else, but the issue only became apparent after the upgrade. No other changes have occurred on my end, which is why I ask. I’m trying to narrow the issue down and looking at the obvious sources first.

Can you replicate the problem using the default Twenty Thirteen theme with all other plugins deactivated?

Tell you what, I’m going to ping my server admins to see if they’ve done anything on the backend of our servers before casting weight on the WP 3.6(.1) upgrade. Let’s consider this topic resolved.

If something crops up again, I will have more information to provide. Esmi, thanks for all you do; it’s greatly appreciated.

No probs. ??

In the meantime, it might be worth turning debug on and enabling error logging to see if that throws anything up. Also try checking your site’s error logs for possible clues.
