Nothing will open up on your page when you create a new web module, you simply click on backend in your site structure and choose new web module and then call it whatever you want to call it and save it. Then you have to click on the backend file to be able to edit it like any other page in the Wix Editor.
Other than that, I would simply just try logging yourself out completely and clearing your browsers cache and cookies etc and then try logging yourself back in.
If your issue still persists, then contact Wix Support as it isn’t really an issue with code on your site which this forum is intended for.
