templates problem

[amin17]

I have 0.8.8a cacti installed in Linux centos, by mistake I changed something related to the templates

after this most of graphs read with wrong value!

also I got the below ERROR when try to add any new graph:

Created graph: WIMAX-GW - Traffic - |query_ifName|
ERROR: no Data Source associated. Check Template



please help..

I added new data query and graph template, now I can create graphs but it contains nothing.

you can check the attached pic.
