I’ve got the same problem ! For 10 days now, I can no longer upload any documents (well, occasionally the system will let me upload an image, if I try 5 or 6 times). I discovered yesterday morning that the problem ONLY exists in my own computer. When I connect from another computer — using my login and password — the site works a usual. (And none of the other admins is suffering from this problem, and so it’s something lodged in my laptop.)
What can I do, in your opinion ? (I emptied my cache, but nothing changed.)
Thanks in advance for any advice you might be able to offer.
