New Error? Can it be?

V6.1.4

Just rec'd email notifies.php with error, although I can access everything as a user just fine. Can someone tell me what this email means? Other than the obvious Database connect failed.

<div style="border:2px solid red;padding:4px;width:600px;margin:0px auto;">
<div style="text-align:center;background-color:red;color:white;font-weight:bold;">Error</div>
<div style="text-align:center;">Database connect failed</div>
</div>

And yes...I too have the email html showing up.

It means the obvious  .....

Thanks Rumpy.

Yes, it is perfectly clear.

What else could it mean  .....
