Hello guys! 
I am having some trouble with my WordPress website. Every time I try to visit it, I get this message that says “Error Establishing a Database Connection.” It’s pretty frustrating!
I have done some things to try and fix it myself:
- I checked the wp-config file to make sure the username, password, database name, and host are all entered correctly.
- I verified that the database server itself is up and running.
- I used the repair tool in WordPress to see if that would help, but no luck.
- I even contacted my hosting company, but they couldn’t find anything wrong on their end.
I also check this: https://forums.managingwp.io/t/wordpress-persistent-database-connectionsalesforce-dev But I have not found any solution and I am wondering if anyone else has come across this error before. If you have any ideas on how to fix it, I had be super grateful!
Thanks in advance. and your help is really appreciable.
