I'm a new customer to Xenforo and have recently installed the software for my website. However, I have been suffering from intermittent database errors.
I usually experience a blank page with the text:
An unexpected database error occurred. Please try again later.
I have contacted my host provider (Dreamhost), but they assured me that everything looked stable and I haven't been hitting any usage limits, which I should hope so, too, since my site barely has any traffic at the moment.
Taking it upon myself to unearth the problem, I granted myself SFTP privileges and opened my latest error log, where I found the line:
[Sun Jun 15 03:46:52 2014] [error] [client 220.127.116.11] File does not exist: /home/username/mywebsite.com/robots.txt
I reported this to Dreamhost but they simply stated that this isn't related to database errors, and since the majority of sites out there don't contain a robots.txt file, this shouldn't be causing the issue. But that's the only thing coming up in my error log, so if they don't have a clue what's causing the fault, I sure as hell don't!
