Thanks for your response. As you suggested, I uploaded a fresh copy of WordPress (after having deleted the contents of my account), created a new database and ran wordpress/wp-admin/install.php.
I got the error message:
“Can’t select database
We were able to connect to the database server (which means your username and password is okay) but not able to select the xxxxx database.
Are you sure it exists?
Does the user xxxxx have permission to use the xxxxx database?
On some systems the name of your database is prefixed with your username, so it would be like username_xxxxx. Could that be the problem?”
Control Panel shows that the database was created correctly (although there is no data in it), and I checked that the database parameters in wordpress/wp-config.php were correct. I included the secret keys, if that makes any difference.
Having once again started from scratch, I am at a loss as to what to do next. Please, any suggestions??
