Error establishing a database connection.

Hello,

I am have some sort of bug issue with Amember. When I try to log in to the admin portal, I get this error - Error establishing a database connection.

I say "Bug" because I know the system (amember) is still running because I can access login and sign up pages/forms and I can log in to the system that Amember is managing access to.

Also, this error is intermittent and when it goes away, I can check logs and customers were logging in successfully while the error was being displayed.

Another reason I say bug is that there are times where I can get this message in Chrome and FireFox browsers and then try on a Macbook and still get it on Chrome but can access app in Safari.

Usually this error just goes away for no apparent reason and everything is fine. I am concerned that there may be a time where the error does not go away and I can never get back into Amember.

Any thoughts or ideas? This has me very concerned.
