The page isn't redirecting properly

Hi there,

I installed Akaunting to my server and modified permission for admin account. When I clicked Save, it turns to a message: the page isn't redirecting properly. After that, I can't access Akaunting again. It always says the page isn't redirecting properly. Can anybody help me to resolve this issue, please?
Thank you very much for your support!

Check your server's error logs. It could be a firewall issue.
