I wanted to register my account at Layershift but signup failed. Here is the error displayed on my screen.
1. The first thing you should do in this case is try to repeat sign up actions.
2. If it failed again, check if your internet connection is OK (problems with connection can also be a reason for this error).
3. If none of the above worked, use WebDeveloper tool to get more information. Press F12 button on the keyboard to call this tool. Choose the tab "Network" and find out what was the response when you executed "signup" method. Provide support with a response of method "signup".
4. Hosting Provider should be contacted if the reason for the failure is not on user's side.
