After installing and configuring Kohana, I renamed the install.php file (according to the user guide). But when I now go to localhost/kohana, I get the following error:

```
 ErrorException [ 8 ]: Array to string conversion ~ SYSPATH/classes/Kohana/Log/Writer.php [ 81 ]

```

I couldn't find a solution elsewhere on the web. Does anyone have any ideas how this can be fixed? Thanks!
