Blank Admin after upgrading to 1.5.1

I am in the process of upgrading to 1.5.1 from 1.3.5.

The installer went through the first steps during the installation, up to Database Upgrade. The database seemed to update, but I was left in that same window so I then clicked on "Done with Updates".

Instead of moving to System Setup it jumped to Finished, bypassing Sytem Setup, Store Setup and Admin Setup. (I have retried several times and found that System Setup is light grey while the other two are black.)

In the Finished window when I click on the "Click here to go to the Store" button, the store shows up but I get this message:

Your database appears to need patching to a higher level. See Admin->Tools->Server Information to review patch levels.

Also, if I click on the "Click here to open the Admin area" button (in the Finished area) I just get a blank Admin page so I am unable to login and check anything.

Does anyone have any suggestions as to what I should do?

So, just go to your normal Admin URL instead.

Solved the database problem. As the installer had "skipped" some steps, I had tried running again, and in the process messed it up. I found someone else with the same problem and followed your instructions (deleting the database and reinstalling etc.) which did the trick.

I am still however, unable to get the admin login page. The page is totally white. Have changed the name of the admin folder, made both configure.php files read only etc...

Have tried manually changing the admin name in admin configure.php on these three lines as doing so on a previous occasion worked but no luck this time:

define('DIR_WS_ADMIN', '/changed to my new admin folder name/');
define('DIR_WS_HTTPS_ADMIN', '/changed to my new admin folder name/');
define('DIR_FS_ADMIN', '/home/globalpe/public_html/store151.mystoreURL/changed to my new admin folder name/');

Also, during the database upgrade, I got this error message:

SKIPPED: Cannot ADD column get_term_table because it already exists.
SKIPPED: Cannot ADD column get_term_name_field because it already exists.

I hope this might be of help. Thank you in advance!

Solved the problem!

Found the thread: I am getting a blank page (or blank part of a page) http://www.zen-cart.com/content.php?124 and checked the debug log files. Found that I had some Japanese language files missing in the Admin area. Installed them and the login window appeared.
