I am trying to set up a demo site under my existing domain in the form of myexistingdomain.com/subdirectory
For this I have created a subdirectory inside this domain and installed wp there. I double checked database , user name , pw etc , they are all correct in my config.php file but its showing Error connecting database
I have set up many more demo sites before in the same way and they are still active, for example
myexistingdomain.com/demo1
myexistingdomain.com/demo2
myexistingdomain.com/demo3
myexistingdomain.com/demo4
etc
Please advice
Thank you
