Insert Currency goes to homepage

I am running Opencart on SSL and things seem good, the only thing is, when i try clicking Insert on Currency page, it loads the homepage.
I am using Shoppica2 theme
On mouse hover, the link is https://mysite.com/admin/index.php?rout ... 893bfcdcbc

Anyone also experience this problem?

Add: not only currency but all other Localisation Insert button when clicked also goes to homepage.
