I’m getting an expressionengine error when trying to delete a field group. I’ve tried to delete the fields within the group individually but I get the same error. One field is a relationship field. The error is:
```
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Rel_ft::$db
Filename: fieldtypes/ft.rel.php
Line Number: 202
```
Another area occurs when I try to delete the non-relationship field in the group:
```
A Database Error Occurred
Error Number: 1091
Can't DROP 'field_id_56'; check that column/key exists
ALTER TABLE `exp_channel_data` DROP `field_id_56`
Filename: libraries/api/Api_channel_fields.php
Line Number: 428
```
Any ideas?

Hi, BrianPx.

This issue doesn’t occur with newer versions of EE. I’d recommend upgrading.

In the meantime, here is the workaround:
```
what you do is this:
in this file:
expressionengine/fieldtypes/ft.rel.php

replace this text:
$this->db

with this text:
$this->EE->db
```
