Make sure that these permisions are configured corectly:
- Joomla! /tmp folder is writable
- Your upload folder (default is usually /components/com_rsform/uploads) is writable
- The relative path you are trying to access (www.website.com/components/com_rsform/uploads/file.doc) points to the correct absolute path of the upload folder (/var/www/mywebsite/components/com_rsform/uploads)
This can also be generated by the misconfiguration in the upload form component's accepted File Types. The correct way is to put each type on a new line. For example:
doc
jpeg
JPEG
pdf
upload_max_filesize=6M; post_max_size=7M;Always keep the post_max_size larger than the upload_max_filesize.
