I have had my website running for more than a year and this morning I tried to view my site and this is my message, "error establishing a database connection". I can not find easy step by step instructions on how to fix this problem. Please help.
As far as the version of WordPress I always update it but since I can not log on I can not tell you for certain what version I am running.
My whole business is my website so this matter being resolved quickly is important to us.
