So... CI profiler. When it shows in BP admin area it's good to have css property
margin-left: 200px;
for showing profiler block content.
In CI 1.6.3 and lower versions this problem solves by editing code of Profiler Class (Profiler.php) line:326, just updating to this line
$output .= "<div style='margin-left:200px;background-color:#fff;padding:10px;'>";
In CI 1.7.0 in Profiler block content now have a div property - id='codeigniter_profiler' .
$output = "<div id='codeigniter_profiler' style='clear:both;background-color:#fff;padding:10px;'>";
So, I think it's natural to add next line to layout.css file:
#codeigniter_profiler{margin-left:200px}
