I have domain.com and I built domain.com/dev/wpresponsive. I backed up both sites using cPanel's Installatron. Downloaded this plugin, which I think is great, even though I did something wrong and didn't get the results that I am looking for. But anyway, I deleted domain.com and moved domain.com/dev/wpresponsive to domain.com. They have two (2) different databases and the tables are not using the default table prefix of wp_ they are using wtx4lpv0r_ and g8edfyaen_ respectively. I am getting "Error establishing a database connection" and I am not sure why. I did the test before I deployed and I got the "green light" to go ahead with the deployment but no luck. What did I do wrong and how can I fix it if I can? Do you have enough information to assist me?
