Why do I need Centry Portal?
Centry Portal allows you to search and filter all your connected websites. You can also register non-concrete5 websites there. You're able to scan websites for comonly made errors, such as broken links, performance, etc. You'd also use centralized logging to browse through all logs from all websites. Nice and easy.
Will it work with subdomains or in a multi domain environment?
Will it work if I have installations in sub folders?
Yes, since version 2.0.
