How can we help you if you don’t provide us with your website url and don’t explain your website problem in detail and don’t tell which type of error you are receiving?

my website name www.pinturatodo.com it is showing “Error establishing a database connection” why showing this

sorry that i did not mention my url and the problem

From the look of its error, it should be Wordpress-based, right? That error means you may have mistyped one or more information about your database.

you are right @Joo_Nath @MrJunior
wordpress wants to connect to database server at sql302.byetcluster.com
that’s wrong
