Hello everybody, I have Xeams for QNAP and yesterday it has upgraded to version 6.4 build 5997

After this upgrade when I try to open admin console (Myhost:5272) and only appear a white page, the engine is still working because my mail is ok and I can connect user form mail client

but I can't login in admin console!!

I have try to stop and restart app, use different browser and stop and restar NAS but the problem still persist.

Please anyone could help me.

Thank's in Advance
