well, that means any changes being made to the connections file are not being uploaded. If you have edited the connection file to use the correct info to connect to the mysql server, the updates are not making it to the server.
try deleting the connection file on the server, then re uploading.
If you still have problems, compress a file that is successfully connecting to the db into a zip archive.
to send a link, you just need to paste the server address to the page in your reply, pate a link for the page that can successfully connect and a link for the confirm page
