Error establishing a database connection - wordpress

Question

I get this error. The connection details in the wp-config file are correct. I have only been getting this error ever since I sent the website files to my boss to put the website online. I also did a dump of the database to send to him.

Is it at all possible that something he did effected my local copy of the wordpress website? It doesn't seem so...but I have only had this issue since he put it online. Maybe did I remove my database by mistake when I did the dump? Can I check that somehow?

Does a database dump mess up my database? I was the one that did the database dump, to send to him. Did it move my database?

Can I reinstall wordpress as a solution and copy my website into it?

Cheers.

Answer 1

Check if your live server database credentials match with details in your wp-config. your localohost credential might be different from server credential

Secondly check if your boss has restored dump database
