No Data Source associated error after upgrade to 0.8.7i

[awareness2000]

Hi,

After upgrading to version 0.8.7i, i'm getting a 'no Data Source associated' error when I create a new graph:

- Devices->Select Device->Create Graphs for this Host
- Graph type: SNMP interface statistics In/Out bits

I get the following error:
Created graph: S220 - Traffic - |query_ifName|
ERROR: no Data Source associated. Check Template

Did you change the default traffic templates (data t., graph t.)?

I resolved this issue by installing a new instance of cacti. In this installation I exported the templates and imported them in my production instance.

good and recommended move for this type of "issues"
