I have installed an add-on on my test store and everything works fine. Now, time to install it on the live store and i run into a problem. I need to "INSTALL" it, but i am not seeing the right side of the panel in the Module > Order Total (i see it on all other panels though). Here is what i get:

Here is my Module > Order Total when i try to access it:



And from there, if i switch to French, this is what appears:



That made me think it was the French part that was corrupt but it turns out that from there, if i switch to English, i get this:



Whenever i click on Module > Order Total i am back to the first image (be it in French or in English).

I have already replaced all the files in the module/order_total by those from the test store (which is working fine). But it does not solve the problem. I am pretty sure that problem was there BEFORE i installed the add-on cause i remember noticing that one page was different than the others, however, i didn`t know it should have been the same (meaning with somethin on the right side).

Any idea where my problem is and mostly how to fix it? I really dont want to reinstall everything from scratch!
