Prestashop theme configurator error

[Meneer]

Hey there!

 

I'm trying to create a free shop for someone and I want to use the default theme of Prestashop. Strangely though I have some kind of error. When I'm in the theme configuration, every time I want to add or change an item the windows pops open and closed.

 

I put a video on Youtube so you can see the error: https://youtu.be/QvMd9ARAeqA

 

Can anyone help me find a solution?

 

Thanks in advance!

Have you tried on different browser? Do you use AdBlock? I had similar problems with Wordpress - disabling AdBlock resolved them.

 

If this won't help you can try to check javascript console debugger to see if there are any errors reported. In Chrome browser please go press F12 and go to tab "console" and then click item edit button - if something's in the console, please provide screenshot or error messages copy.
