I have previously used OctoPrint successfully but when I tried today I am now getting a new error. Whenever I try to upload a file the progress bar completes but I then get an error message:
Upload Failed - Could not upload the. Make sure that it is a valid file with one of these extensions: .g, .gco, .gcode, .stl
I have tried different files and have rebooted several times to no avail.
I am running Octoprint 1.3.8 with an Anet A8 running Marlin. The SD card failed and I have been using Octoprint as the only method of printing 3D files.
Any help would be appreciated.
