Not sure what is happening. Looks like the theme is not properly copied into your installation. There should be no need to apply all these changes...again.
The best way is to delete the current theme, download the entire repository (no other way unfortunately) and then put the "new" theme in your `themes` folder.
The function `getAlbumLinkURL()` has been deprecated since 1.4.6
You should use `getAlbumURL()` instead.
There should be no errors using `getAlbumURL()` if you really use the official 1.4.8 release.

Please, never change core files!
Go to Admin -> Options -> Security -> check [i]User name[/i]
There is a missing closing `</li>` after the "ARCHIVE" link.
My guess is that you either copied/pasted only parts of the release and theme to suit your needs or that things went wrong trying to overwrite file/folders.
Please always install the latest [b]complete[/b] release and/or themes and first delete "old" files/folders.
It makes it very difficult for us to give support if things are messed up or not up-to-date
Note that version 1.4.9 is available for some time now.
