Board3

In the ACP I can't find a thing to edit/delete the blocks
At the installing i change this 2 files:
http://forum.potterdome.com/install.xml
http://forum.potterdome.com/xml/subsilver2.xml

So you can read here that I installed it good I think, but can't find mod in the acp
but must add only this line ...

i've posted this earlier on phpbb.nl and phpbb.com but they could't help me.
The gave the advise to go through this supportboard. It's about the blocks in board3 offcourse
