I have enable already json-rpc and create a valid ssl certificate , added to my webserver. However i cannot add my survey on the application. Could you help me?

I will reply to myself and to give answers to other users.
It was my fault that I only set my web address only on the form eg. www.example.com and not the full address www.example.com/id-of-survey . After that i can use offlinesurveys

Setting the full address of the survey, including the ID, in the form (e.g, www.example.com/id-of-survey ) resolved the issue and allowed you to use the OfflineSurveys app successfully. Dynamons world mod apk download   

Hello, I have the same problem with Offline Surveys but I don't understand how to fix it. Could you tell me what to do? Thanks
