SOmething strange happened today. noone can upload files as Documents.
Server configuration was not changed a bit.
When user posts upload Ajax cursos is showsn and that is all, no errors no nothing. After some time, cursor wanishes, uploadin dialog is still there and that is it.
When i check tmp folder, I can find file uploaded. For some reason, uploading process stops there. File is not moved to upload, not database populated.
This is not a problem of PHP upload settings. Nothing in serer configuration changed since yesterday, when it worked. There is alos more than enogh free space for file storage.
Ajax shows nothing, log is empty, and even php does not show any error. It just silently does not work.
How can I check what is the problem?
