Cannot configure modules when trying to create a product

[Moryl]

Hello,
I'm trying to create a new product, but when I try to configure the modules to customize it under "Modules" tab in the product, I cannot do it...
Can anyone help me solving this bug? I just upgraded PrestaShop from 1.6 to 1.7
Thanks in advice!

Which modules do you have installed? Have you checked if these are compatible with 1.7?
Is there any error shown, especially when debug mode is switched on?

You can do

• Enable Debug mode in Prestashop: https://www.prestashop.com/forums/topic/575132-how-to-enable-debug-mode-on-prestashop-17-and-older-versions-turn-on-error-reporting-blank-page/
• open Console in Chrome Dev tools and reload that link product to see error message

The modules were included in the theme that I bought. I never had problem with the compatbility so I think it's not that the problem.
I also asked to the author of the theme and modules but he said that none of his customers had my problem...
