Dear SeaTable Admins,

## The problem:

Do you run your own SeaTable Server and after an update to version 4.2 you only get an “Error” on the homepage of SeaTable?

Then it might be the problem, that you activated **departments** anytime in the past, and now you have this configuration problem.

## Look for the errors:

Open the `dtable_web.log` with, for example the command `fail -f dtable_web.log` and see if this error occurs if you open the homepage of SeaTable with your browser. If you see this error message, your ran into this problem:

```auto

    for dep_id in department.path.strip('/').split('/'):
AttributeError: 'NoneType' object has no attribute 'strip'

```

## The solution

Open your `dtable_web_settings.py` and comment or remove these two entries.

```auto
DISABLE_ADDRESSBOOK_V1 = True
ENABLE_ADDRESSBOOK_V2 = True

```

Alternatively, you can set both values to `False`.

Then restart SeaTable with `seatable.sh restart` and the problem will be resolved.
