We’ve run into a problem and are unable to handle this request right now. 
Please check back in a little while.

I am guessing that the one on the subdomain is also caused by a database error. I checked the database credentials inside my wp-config.php file and it seems to be correct. The website was working fine yesterday. That was around 10P.M. CST. Right now, it is 11A.M. CST, and I cannot access them. I have been trying for almost an hour.

The error has been resolved after just waiting a bit. :tada: But I am still curious as to why it happened.

This may happened coz failed in DB server down on that moment you tried!

Your account is on database server SQL213, which is currently overloaded. I wrote more about that here:
