I host my website at dreamhost and I remarked variables loses when you upload a file >100MB (or earlier, at any case it works fine for 1KB, 10MB).
The form, http://www.hirvine.com/provmedia/#Form
You have to enter some info like name and email
In the next form you can upload a file
The third page confirms you wether the upload and mail send was succesfully
When the file is smaller then a big file say 100MB. Everythings ok, but when it’s bigger it fails and my script tells me (isset($_Form)) variables are lost. But it worked with files smaller than the big file.
Why can’t I upload more than 100MB?
Did I forget something? Yes I allow such a size
(You are free to try out the script, need source, just ask , but I’m sure I missed a line)
