Hi there,
About 4-5 days ago our site stopped sending out emails and the test email showed an authentication error with the SMTP login. Nothing had changed with the settings or our UN/PW for SMTP. We were one version behind on the plugin so we tried updating to the newest version but receive the same error. Now even when we back up to an even older version of the plugin, it still gives this error. Unfortunately we am unable to update to any newer version of wordpress on the site at this time to to other plugin conflicts. We are also not able to turn off authentication.
I saw a post from about 4 months back were someone was experiencing this same error but it seems that was resolved. Not sure if it’s a similar issue or not.
Thanks for your time!
