Slideshow CK causes conflict

The first one in the list is the facebook error. The second is due to slideshow ("Uncaught ReferenceError: Slideshowck is not defined"). Anyway, I have realized that my template is not updated. So, I will update it, and see if I solve the problem.

clear your browser cache, this shall fix it

by my side as said it works in Chrome

I even changed PC and cleared all my browser cache, but with Chrome the issue is still there (I tried with Microsoft Edge, and everything is ok).

strange. Just tested in Chrome with another computer, it works too by my side !
I don't understand why you have this error then

try to edit the source of the page, then click on the camera.min.js file that is loaded and send me a print screen of the beginning of the Class

It's strange for me, too....

I've done what you asked to me. You can check here ( drive.google.com/file/d/0B3cHZw9iPWZuMWl...U00/view?usp=sharing ) the all page that opens after clicking on the camera.min.js file.

this file is not correct
please use the same file in the 1.4.2 version that you have downloaded. You shall not have the same.
