Description of my issue:
I realized that today I got an SMTP error! Cannot Authenticate message when I logged in to backend Joomla. Below is the debug message as listed below:
SMTP Error! Could not authenticate.

I am trying to figure out what might have caused this issue, if Admin Tools could be a cause. All my smtp login settings have not been changed at all, but authentication failed anyhow. Please advise.
Thanks.
