session_write_close(): write failed: No space left on device
The disk on your server is full. Delete files to make space or increase the size of the disk.
What error code is the web server giving you? I mean like "404 - page not found"?
My best guess with what little info I have is, either phpmyadmin is not in your web server's directory tree, or it's not "aliased" in like an Apache config file (if the files are truly not in your web tree).
