Can't edit Lightbox settings in Admin panel

Hi,

I have come across a very bizarre problem.

My DB and website work perfectly and my DB tables have the prefix of the default 'zen_'

However, i am trying to change this to 'zen_BM_'

To do this i have used CoffeeCup HTML editor to do the following:

1. Exported all of the SQL for the tables
2. Done a find and replace to update 'zen_' to 'zen_BM_'
3. Import SQL into the database so i end up with 2 sets of data and tables... one with the prefix 'zen_' and the other 'zen_BM_'

The Website front end works fine when i update both of the configure.php files:

define('DB_PREFIX', 'zen_');

TO

define('DB_PREFIX', 'zen_BM_');

HOWEVER, when i log into the 'Admin' panel a problem arises.

When Trying to edit the 'Zen Lightbox' setting in the 'Configuration' menu, the Info panel to the right of the screen disappears.
Meaning i can't update the settings!??!!?

However when i revert back to the 'zen_' database everything is ok.

I'm baffled by this, as the 2 sites are a replica of each other, so don't know where to start looking for a possible solution.

I hope someone has come across a similar scenario before, or is able to advise a possible solution, as i am looking to run several sets of data from the 1 database.

Many thanks

Andy

p.s. if screenshots will help to visualise the problem, i can add some later.

I'm not really sure what you're trying to acheive here, but a simpler solution might just be to create a copy of your database and re-name it?
