Mambo 4.5.4 + Gallery 2.1.2 Full + com_gallery2_v2.0.13-beta2 = blank Album Management

Hello,

I've read a great deal of the post here so I don't think this is a repeat problem but apologies if it is.

I have installed and configured Gallery 2.1.2 no problems, I can create gallery's etc.
I have also installed and configured v2.0.13-beta2 (and tried others) of the gallery bridge. Here is the config:

Full Server Path to G2: /users/home/me/domains/somedomain.com/web/public/g2/
URL to G2: http://www.somedomain.com/g2/main.php
Path to Joomla: /

I have synced the users.

But still I get a blank page (just the mambo header and footer) when I click on Album Management.

Any ideas? Any help will be greatly appreciated.

Thanks,

P.S. I also tried the same with Joomla 1.0.11 and got the exact same problem.
