@nesrine3ayadi,
You need to enable debug mode in your store and debug request which is sent for product edit in your browser, using DevTools, so:
Thanks!



So ?
@nesrine3ayadi, you have an error 500 in your console
Click on the Network tab

you should see the error message in "Response" or "Preview" tab
Thanks!

@nesrine3ayadi, thanks to provide me all the exception displayed.
Thanks!




Do you mean this !
@nesrine3ayadi, this issue occurs with the posstaticblocks module.

As it's not a module provided by Prestashop, we can't do anything with this.
You should contact the module author via your addons.prestashop.com account, they are the only ones to help you with it.
Thanks!
