I was building a post in the WYSIWYG editor and went to add a picture. A picture of my cat. (yes, I am one of those.)
The picture was in a folder on my Linux desktop machine, the folder’s name is #Caturday.
Publii could not complete this action. It hung on “Uploading…”
When I restarted the process and renamed the folder Caturday, the upload was immediately successful.
