I have a site running U7.7.2, and when I log in with administrator privileges, or any of the editors log in, nobody can save any CSS files.
No error is displayed to the user, but the dev console shows Error 417 Expectation Failed
https://(site)/umbraco/RestServices/SaveFile/SaveStylesheet 417 (Expectation Failed)
The trace log that I can get from the developer pane doesn’t have any record or any errors related to this.
I tested adding a comment to a JavaScript file with the backoffice editor, and that saves correctly.
I have been out of the Umbraco world for a while (I’m only the backup support person, and nobody even TOLD me I was the backup until today). I see that there was a problem in 7.6.5 with error 417 but it was corrected in 7.6.6, so I’m assuming (perhaps incorrectly) that is also fixed in 7.7.2. It also seems like that was manifesting differently.
I don’t have the ability to deploy changes currently, but I’m working on getting that access. For now I’m limited to what I can do through the backoffice. Any ideas?
