Take a look around for the directory it references. /minamaze/admin/
Let me know if you find it, because it is absent in my 1.1.7 copy.
Definitely. It is looking for files within /minamaze/admin/main/ but minamaze 1.1.7 download doesn’t include an /admin/ directory. I went and got 1.1.6 as a stopgap remedy.
This seems like a major oversight as /minamaze/functions.php contains references to this directory on lines 17 through 27.
Furthermore there are references to a /minamaze/lib directory which is also absent.
I feel like the developer perhaps omitted a couple of directories. Either that or they made major structure changes and left some old stuff in there (seems less likely).
