Hello,
thanks for your very quick answer and your test.
For me the module does not install (remains blocked on the installation window) and causes an error when I restart the backoffice.
This is a new version of prestashop 1.7.5 with the theme warehouse, without importing customer data, sales ...
On a server with Litespped installed of course, which works sane problem on version 1.7.3.2
thank you for your attention
and sorry for my english
