Re: [ispro] Strange admin.php problem
Looks like you've overwritten a file on your ftp with your internal header file.
It'll be therefore using your internal header.php file, which will not include the CMSB css references, hence your list styling.
Re-install the CMSB over FTP (so it doesn't overwrite your existing schemas etc, just like you'd with with an upgrade) and try it again...
