Hello John,
Sorry for the issues with the visual editor not working. This is possibly a WordPress issue with caching. We do not have enough information from you in order to troubleshoot the issue. It doesn’t seem to be a common problem with BoldGrid users, but there are different reports in the WordPress Support Forum concerning issues with the Visual editor. They vary based on the version of WordPress you are running. Check out this post based on WordPress 4.7. There’s also another support post based on version 4.8, but it describes the issue as the Visual and Text editors not working. However, both may provide solutions that help to solve your issue. If you want us to continue looking into the matter, please provide your website’s domain and information on the versions of WordPress (plug plugins and themes) and BoldGrid that you have loaded. Additionally, the exact steps you’re taking leading to the error would help us investigate the issue.
