Hello !
Sorry for the delay, I was working on an other project.
I’v reinstalled Woocommerce last version (4.0.1) and now it seems to work fine. I don’t know what happened last week, maybe the fatal error I had was caused by another plugin or the database not well updated …
Anyway, it works now, so thanks for your time !
Thank you ! It works and you were right, the customs templates were not up to date.
PS: Just for info, I had to downgrade woocommerce because the plugin is not working with the lastest version. I guess it will be with the next update.
Regards,
Maureen
