Hello,
I get these issue on network google inspect when I try to update quantity on presta backend:
DevTools failed to load source map: Could not load content for /adminxxx/themes/default/css/admin-theme.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
Also when I rename folder modules to modules_ everything on backend work fine.
I think there is issue with ajax or java.
Prestashop 1.6.1.24
Mysql 5.6.4
Thank you.
