avatar cropping tool is not working

I can't get avatar cropping tool to work. It doesn't work on any browser. can anyone help me

Hello

Do you receive any PHP error/warning message on the page? If not, try to install FireBug extension in FireFox browser. Then try to open avatar page when FireBug is activated and use the cropping tool. I think you should receive some JavaScript error message. It will help you to resolve the issue. 

 thank you but it shows no errors is if the avatar cropping tool is not even there is there a way to enable it or see if I'm missing a scrip for it?

Hello

The tool should be loaded automatically. You cannot enable/disable it.

Did you check it in FireBug? The code can be affected with some other error in JavaScript. In this case it won't be loaded correctly.

I found the solution to this

it appears that if you edit or add code to your header.php or subheader.php a lot of things in your site go missing.

like my cropping tool in avatar section

hope this helps people
