Hi Arlen, On windows 7 with Firefox, I also have a lot of XMLHttpRequest: 412 errors, with the following error in TiddlyWiki: "TypeError: xhr is undefined" and in the command line:
[2017-10-25T17:57:45.141+-200] PUT 127.0.0.1 200 127.0.0.1 /my_wiki/No tes.html 494.586 ms - - 412 ifmatch "1125899906935583-8410702-1508947064000" 412 etag "1125899906935583-8410702-1508947065000" 412 caused by difference in modified I hope you can fin a solution: TiddlyServer is otherwise really useful. Best regards.
