Unable To Register New User Or Login

I installed Multi-vendor, and both admin and vendor pges work…

but customer register or login fail error 404, store_url/login or store_url/profiles-add not found

I can’t find any discussion of configuring these…

Try to disable the SEO module at first

please check this article

the http server dod not have mod-rewrite enabled, and did not allow local .htaccess control

in this case please try to disable module “SEO” under menu “Add-ons” → “Manage add-ons” in cs-cart admin panel

p.s. it seems that your server is not Apache and appropriate server extension for seo links are not configured properly
