Technical issues by answering questions to guests

Hi, I'm trying to answer many questions to my guests, however I'm having some technical difficulties. Systems shows me following message "Sorry, something went wrong. Please, try again later". 

I have tried it several times, however results is the same always. 

Can you help me out here? Have you experienced before problems like this? Does it have to do with the rights / kind of account I have? I'm supposed to be the Administrator, however my business partner could be declared as the owner and I as a secondary account. 

I appreciate your help.
