Wordpress first run show a 404 error

I downloaded the lates wordpress version then uncompressed it. Because I had already an old version of wordpress, I have wp tables on my local server. Anyway,开发者_如何学编程 I don't think it comes from the old content.

After that, I set up the right server and database values in the "wp-config.php" file. Then, when I wanted to run WordPress (myblog/index.php), nothing happens and, worse, a 404 error.

I thought it was my easyphp server, so I uploaded the whole database and wordpress on my website. Nothing but a 404 error page again even if the file does exist!

Can you help me please? should I activate something to enable the first run?

Thank you very much. Regards.

Did you

1) Upload the files to the correct location on the server?
2) Upload the correct files? (e.g are the actual WordPress files contained in a sub folder?
3) Ensure the correct privileges are set on the folder and files?
4) Follow the instructions in the downloaded package (e.g. run install.php)?

Did you run the install script? After copying the files to the server, you must run the install script at myblog/wp-admin/install.php

try and go to Dashboard > Settings > Permalinks and just click "Save Changes" and see if that helps
