General Support: can't upload single file

i tried the import function and it works fine.
but when i try to upload a single one, a most important feature in my case, it fails without errors. just the warning symbol.

i've done a little debug on the script and i found that the gallery stops in the file "plog-admin-functions.php" in the following row:
"if (!rename($tmpname,$final_fqfn)) {"

does anyone has any idea? have i to contact my mantainer? and what should i ask for?

thanks a lot,
nicola

Strange that the import works but not the regular upload... If it is having trouble renaming your file, it is most likely running into permission problems. Make sure your images directory is writable and also make sure that you are not running safe mode, these are the two most likely scenarios.
