Index - Blank page, BO works fine

[micronet]

Hello everyone,

 

I just got a blank index page out of nowhere. The website was working fine without any problems.

 

I was trying to add a new voucher code and at the same time refreshed the FO and ... blank

After 10 minutes someone placed an order, not sure how as I tried to check the page from few different IP and there was nothing .. 

 

Back office works fine, without any problems. 

The maintenance page appears fine if I turn it on.

 

Version: 1.6.1.8

 

 

Any ideas what it could be? Need your help urgently guys as we are having sales campaign at the moment and loosing profit.

Thank you in advance!
