I have a very high probability of not being able to upload files to my area (Not sharing). They are not affected by filename, filename length, file size, file type, or language used.
For example, a document is scanned with a copier and processed into PDF. I do it twice and make two PDF files. When I try to upload them, one succeeds and one fails.
I will be warned as below.
“You don’t have permission to upload or create files here.”
This happens whether I use a web browser or a WebDAV connection (on Windows).
How can I increase the success rate of file uploads?
