Minor cosmetic issue

I have a FreePBX box working as a call conference server only. The networks statistic on the main admin page always shows zero for transmit and receive. I did check to make sure /proc/net/dev is readable and it is. I have another FreePBX box being used for voicemail and IVR and these stats update fine. Boxes are the same hardware and only differ in the services they provide.

Any ideas?

thanks again,
