Hi,

I created for example mytemp folder in root of my site and added this code to uploader php code :

$uploader->TempDirectory="/mytemp"; 

and set permission just like this  and tested and tested by 777 again  :

 but after upload clicked i recived these errors ( i select "watermark.png" for upload) :

Server side exception, failed to upload watermark.png

Debug Information:move_uploaded_file(): Unable to move '/tmp/phpLYKbsg' to '/mytemp/uploading.79c6de73-20f7-95c4-96f3-067d91702e2c.watermark.png.resx' , failed to move /tmp/phpLYKbsg to /mytemp/uploading.79c6de73-20f7-95c4-96f3-067d91702e2c.watermark.png.resx' , at /path of phpuploader folder /include_phpuploader.php line 1215

and in next trying i recived these errors : 

Unable to find file 6bebef11-129a-2e69-0b7a-c79f8f4fdb15 in /mytemp

or

html5 : The upload task is interrupted!
