I have a form on my website to upload files to the server. I uploaded several files this morning when I suddenly got a “Page not found” error. I would select a file and click submit, wait a few seconds and then the file not found page shows up. So I checked to see if the file was still there. It is. The file size limit is set at 2000 KB and the files I am uploading are only 200KB. I have no idea how to troubleshoot this. I thought the problem would have to be in the session headers but they are very simple, just session_start(); and have worked for months. I contacted the webserver technicians and asked if there were limits to the file space on the server but there is plenty of room. I asked if they had changed permissions or modified the php setting but nothing has been changed.
Any ideas would be appreciated.
PS. What is the best medication for PHP headaches?
