Hello,

I checked with Firefox and IE 8-9 and did not see any error, can you tell me where url and browser you found errors ?

With error 2 you can remove otscript.js

Hello,

It is www.thepawsociety.co.uk

I go the error in explorer 8.0

The menu's don't work and thought it might be because of this java error.

I would really love the user guide too as I can't find it and I am struggling to configure.
Thanks.
