Logo Sidebox Help

[discoverytdi]

I've been trying to creat extra sideboxes named logo, logoa, logob first 2 install no problem but as soon as I install logob it breaks my site. Renamed all the folders and files as per read me even tried giving them different names ie paylal_sidebox, delivery_sidebox but they still give the same result, is there something I'm missing
