finished installation but cant log in

I have uploaded and followed the installation instructions for opencart. However when get to the, congratulations page, you have successfully installed opencart, and it says, click here to log in to admin panel or click to go to shop front, the page loads but there is nothing there..

Does anybody know what may have gone wrong?

As a first step, try re-uploading the files. You may be missing some files
See if that works

Also check the file and folder permissions to make sure they are correct and that your session folder (wherever that is!) is writable etc.
