buttons "save" and "save and stay" in the product details pages takes about 15 seconds to load (the page loads while the buttons remain Loading), even after all the times that you click it to save. This happens to me both locally and remotely, after upgrading from version 1.6.0.9 to 1.6.0.11 prestashop. I also did an experiment: after installing a test site with version 1.6.0.9, I went to change a product and I noticed that the buttons mentioned above were loaded immediately and then properly. I then updated to version 1.6.0.11 via the module prestashop "one click update" and then I returned to modify the product to see if the buttons "Save" and "Save and stay" were loaded again quickly, but no !!! !!!!! Has anyone encountered the same problem and solved it?
