Adding text to Registration Form
Well next time something fails, check the logs and see what happens.
If it doesn't happen again, it means that for some reason you need a more robust way to send emails, like this plugin (or some other simpler).
Sometimes it is needed because of several technical limitations of hosting or the receipient servers.
Will do! Thanks again for all your help. I appreciate it.
I will monitor, and if there are any future failures I can't interpret, I will call on you.
Have a good day.
