Hi, svswordpress, & welcome.
It’d be very helpful if you’d provide a link to your site. This is often an error that occurs w/older PHP versions. You don’t say who your host is, but often there is a facility in the website control panel to change the PHP version. You might try that.
Have you created a database for this WordPress install & connected the install to the database? Conversely, did you use some sort of script autoinstaller in your control panel to do that for you?
Host – Lunarpages
Current site – Sweetwatervideoservices.com
I am trying to replace this by using ftp to copy a new version of Word Press into the public_html folder.
I then use my browser to launch the site and then I get the error message. I understood I would be prompted to connect to a database when I launch a new version of word press.
svswordpress, I’m seeing your site. You’ll need to edit your wp-config.php & make sure the database hostname, username, & password is correct, but I suspect it is, else I wouldn’t be seeing the site. I also got a login page when I went to wp-admin.
what did you type to access the site when you got that error?
