Temp folder seems to be not valid

[J4H]

Hi,
I use smf 1.1.12 & d.pro 2.0.
I modify my php.ini on my host to 10 MB.(FATCOW).
I can upload using smf default attachments but via d.pro if i upload more than 1 MB I have this error :     Temp folder seems to be not valid
I check temp folder in php.ini and is set to : "" and my host tell me means default folder.
So via smf default attachments work 7-9 MB and via d.pro if upload more than 1 MB : Temp folder seems to be not valid.
Can you help me please ?

Disable the progress bar setting looks like your host does not support it.
