The mobile response was working just fine until the past couple of days. When trying to access website the home page is blank. At first I thought it might be internet issue and I tried on a different device and the same issue occurs. I am not sure what could be done to resolve issue, please advice as of what we need to do.
Did you made any changes in code? If not then the responsive site must work fine. It would be great if you provide your site Url too. Once deactivate all the plugins that you have installed in your site and check whether the same problem occurs or not.
