Full Version: Users with usernames containing turkish capital i (İ) can't login

I have a local MyBB installation on my computer (windows) which works with all kinds of usernames like:

İ ĞŞÜğşÇçIıı İİİ Türkçe


The same site is deployed to a host. Now when users with that kind of usernames try to login, it always fails with "incorrect username/password combination".

I checked MYSQL table and column collations, they are the same utf8_general_ci collation on local and host

I also checked login form post values and headers, they are the same on local and host too.

What can the issue be? Also themes doesn't matter too, both local and host are using the same default official MyBB theme.
