Script repository, no location for

I have been working through the e-neutrons tutorial of the Mantid script repository. I have downloaded the repository for Mantid plot however the tutorial says the file “” needs to be installed from the muesr folder which is in the muon folder. Clicking on the file should automatically download the file however the download failed, producing a warning which says the file could not be found at . Is this the correct link for the file location?
