The problem is with permissions. 1.7.5.0 repeats old bugs (typical for presta 😣 ). It works on localhost because you have full access there, but on the server it all dependes on folders' and files' permissions and it's simply wrong. Set 755 on all folders and 644 on all files. Then delete /var/cache/ content (/dev and /prod)
