Product combinations

[JJPato]

Don't understand how, but I can not generate any Product Combination in the Admin side.

I have already checked all the new modules that I have installed and all the modifications that I have done but nothing seems to fix it.

When you press "Generate" the rows doesn't appear. I have checked in the database and they are there. But I am guessing that there are some js problem stoping the properly view. 

I'm leaving some screenshots. You can also see that the "combinations-bulk-form" is like loading.... but it never ends.
I am just adding 2 attributes on a 25 product store. It is not a server memory problem or something like that.

Already erease cache at PS and also Manually
