I keep attempting to login to change my mac addresses for my donations and I'm getting this error: A PHP Error was encountered Severity: Warning Message: mysql_real_escape_string(): Access denied for user ''@'localhost' (using password: NO) Filename: controllers/main.php Line Number: 537...

I have a huge dilemma, I have 3 donations that I purchased from a reseller, however I cannot find my order numbers for them so therefore I cannot change my macs. I tried contacting them but to no avail, can an admin please assist me?
