Hi there, I am using this plugin for a long time and never had any issue but recently I start getting these errors in the WordPress dashboard almost every couple of days
EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.4.0 logged this error during the last time it tried to send an email:
A valid URL was not provided.
Consider running an email test after fixing it.When I run the Test email It works without any problem, I also tested email deliverability in general from WordPress actions like resetting the password, creating order and it seems to be working. How can I figure out what causes that error? I use Mailgun for emails
