Help with Java

I recently updated my Java, but now whenever I go to a skin, the 3D render has a white box with an error, and it says that my security settings have blocked the plugin from loading. I enabled all plugins to automagically load on PMC, but the error still appears. When I click more details, I get this:

Java Plug-in 10.51.2.13
Using JRE version 1.7.0_51-b13 Java HotSpot(TM) 64-Bit Server VM
User home directory = /Users/------
----------------------------------------------------
c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
m: print memory usage

q: hide console
r: reload policy configuration
s: dump system and deployment properties
t: dump thread list
v: dump thread stack
x: clear classloader cache
0-5: set trace level to <n>

Please help me with whatever help you can provide. Thank you.
