Dear experts,
I have WP Mail SMTP installed on two sites, both hosted by the same provider and using the same SMTP server. At first, both worked normally, but, at a certain point, one of them stopped working, for some reason. Both are configured exactly the same way.
Can anyone suggest any checks I can do?
Thank you in advance.
