Question: I have one store (base) and I need to create another root category to test a new strucutre out so my plan was to create a new `Root Category` and then tell magmi to import into that... No such luck.

I've created a new root category called Testing.

Here is a sample of the Data.

```
sku,categories
12345, [Testing]/Level1;;[Testing]/Level1/Level2;;[Testing]/Level1/Level2/Level3

```

Every time I try and import this, I get this error:

`On the fly category creator/importer v0.2.5 - Cannot find site root with names : Testing,Testing,Testing`

Can anyone help me out with this one?

Answer: 
Can you please add the following to the index.php of your website 

```
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

```
Can you try to disable any custom module one by one to see that causes the issue?

That may be cause by a faulty module or conflicting modules.
