thanks plugin css - help

[Kowak]

The account that I sent you is a normal member account with theme changed, why can't you do anything?

You call thankyoulike script and so thanks script, theres no troubles, because thanyoulike would not exist, the problem instead on your jQuery, that because some things would not work fine, when you change your code you can use any mod as you wish xD. But for now i can't do anything.

I didn't understand this part

EDIT1

Do I have to make a particular test account for you? I thought you needed a normal member account.

EDIT2

And how can I do for call it?
I can ask the theme creator but the fact is that it's a plugin problem, not theme problem
