Re: K2 Server/Service error "String cannot have zero length

Hi  @byambajargal , 

Does this happen everytime you try access something K2 related or only on certain sites etc? 
Reason for asking is that this might help narrow down the problem. 

Additionally have you taken a look at this: https://community.k2.com/t5/K2-Net-Blackpoint/K2-Server-Service-error-quot-String-cannot-have-zero-length-quot/td-p/4001?nobounce

Have you made any changes to your settings recently that could warrant this behaviour?
