Default SuperSU error messages and not working?

Hi,
Lately the supersu so from chainfire is not working well. If I open an app that requires root e.g mobile Odin it loads for ever without opining. Then the message that mobile Odin has root permission comes every 10 second til I reboot. I thing this happened after I updated supersu app. But after uinstall it is still the same. The app needs to be updated when I open it but installation fails even if I reboot and try again.

Rooted with cf auto root and on stock with cwm.

Any idea what's wrong?

Thanks
