Blank WP-admin page

Hi,

I have the Newsmag Theme (ver. 2.2) installed and custmized on my local machine.
Everything works as aspected.

After uploading all files to the public server, the theme is not working (displaying only the header) and
the wp-admin page keeps blank.

Of course all the necassary configuration within the database was done.
I also changed the functions.php back to the original one – no difference.

Could you please provide a hint where to look.
What are the first files loaded when the newsmag is activated?

I also tried to disable all plugins, same.
The only thing is to rename the theme folder and then go back and work with the fall back theme.

Thanks.

solved – the problem was a leading blank in td_block.php
