I have a user based in another country who cannot upload documents to a document library. After clicking Upload she is presented with the Upload dialogue, but after browsing to the file and clicking upload the same screen is reloaded again. No error message is shown and no document is uploaded.
This only seems to be happening from her location. Here in the UK it is working absolutely fine.
Any ideas what may be causing this?
EDIT: It turns out she is able to upload documents, but it takes as many as 7 attempts to do so. The above keeps happening for a number of attempts until it eventually works.
