I think this might be a server-side issue more than a bug, but on both an Ubuntu 10.04 installation and an Ubuntu 12.04 installation (the current one) when trying to use the Ajax FTP service, uploads cannot be performed.
It gives a 413 error and says something about "cannot create temporary copy to save on the server". That's not exact words, but it's close enough.
This is version 1.1.0-beta1
Is this a server problem like I expect? And if so, how can I fix it?
Take a look into ftp logs 
Where can I find the FTP logs?
I looked into apache's default-error.log and error.log (as I was told to in the IRC channel) but I couldn't find anything related to the incident 
OK, i can confirm this with Upload. It seem's something is wrong with tmp detection. I will take a look at it.
Thanks
Thanks
Looking forward to seeing it fixed. It's the only thing stopping me from using this on a production-scale 
Quickfix:
add to php.in at open_base_dir directive
in
/var/www/fcgi/master/php5/
:/tmp
Edit
/var/www/imscp/gui/public/tools/filemanager/conf/
"bootstrap_reprosities"
"TMP_UPLOAD" => "/tmp"
