Glow text in my forum

Hello, when i add this to my forum it doesn't work, even though it works here and in any other forum !
hello

Code:

[blur]hello[/blur]

Hi,

Try adding this code in Admin CP > Display > Colors > CSS...

Code:

.blur {
display: inline-block;
color: red !important;
text-shadow: 0 0 6px #AAAAAA;
}

It gives me this

Code:

Detected error
We have counted a different number of "{" and of "}". It means your CSS risks to be not valid and will not be posted correctly on your forum.

We advise you to reread your code.

You must have added the code incorrectly. Remove it and try adding it again.
Make sure you include both opening and closing curly braces.

Still giving me the message, can you make sure that the code is correct ?

Code:

.blur {
display: inline-block;
color: red !important;
text-shadow: 0 0 6px #AAAAAA;
}

The code is correct and I have tried it. Try removing that code and see if the error is still there. If so, the problem is with other codes which are already there.

How can i thank you ? Your just so helpful & patient !
thanks alot it worked !
