Hi, krpano testing server doesn't work:
Error 404: Not Found
File not found
I dragged the folder to the Local Folder space and the address http://127.0.0.1:8090 was generated. When clicking on its link, the error 404 appears.
(Testing on Windows 10, 64 bits)
Testing too with Local Host setting 8090 port: http://localhost:8090/ on Mozilla Firefox (120.0) and Edge (126.0.2592.81 -64bits-)
