WPML JS error

Hi guys

There is a JS error preventing the 'duplicate' checkbox from displaying the 'Duplicate' button when editing a post.

The JS error can be found in the file 'res/js/scripts.js' on line 27

Please change:
```
if(jQuery('#post ').find('input[name="icl_dupes[]"]:checked'.length > 0)){
```
to:
```
if( jQuery('#post').find('input[name="icl_dupes[]"]:checked').length > 0 ){
```

This is found in version 3.6.2 of WPML

Thanks
