Hello Everyone! I've buy a new domain for host my website with PrestaShop but I'm very scarce! I've uploaded manually the file of CMS and I've installed as well, the backoffice works but some menu are impossible to use, as you can see in image below. And the issue much important is that the frontoffice don't work! If I surf on it, after some seconds of loadings, it print me "ERR_TOO_MANY_REDIRECTS". But some pages of the website works, let me take an example: example.com/ (MAKE ERROR) example.com/admin (not the backoffice access, THE PAGE WORKS with error 404) If you could help me I would be very grateful.
