all of a sudden, UPLOADING of files in all my forms didnt work.
i tried may things as i had googled it. i tested the code, $_FILES seemed to be empty.

free-up /tmp folder
check php.ini; increase post_max_size, upload_max_filesize, memory_limit
restart apache after each configuration
folders are not read only.
users have read/write permissions.
forms already have enctype="multipart/form-data"

when i tried var_dump($_FILES);
array(0) { } appears.
