This error will pop up if the browser does not allow local access to your files for the HTML5 output. To avoid this locally (your computer), do one of three things:
- open the project directly from Pano2VR/Object2VR by clicking the Open output file button, or
- access the output via the integrated web server, or
- upload the project to your web server, or
- create a desktop application.
Sometimes, you’ll need to send the project to a client, and they’ll see this error, too. To avoid this issue, simply select, Embedded XML, in the normal template of the HTML file.
