known but intercepted issues

– Safari browsers on Windows platforms are not able to upload multiple files at once – SFS turns multiple upload support for Safari browsers on Windows platforms automatically off – single uploads works although
– Drag and Drop functionality doesn’t work on Internet Explorer Versions smaller as 10.0 (incl. MSIE10.0 with compatibility mode = MSIE7.0) – SFS just displays another message without the drag and drop information on upload page

Filesize Hints

The main troublemaker  :)
The maximum used filesize is depending on various circumstances. And the filesize you set here will be
recalculated to avoid upload troubles (if you set a higher value as your webserver?s config allows).

These are post_max_size and upload_max_filesize

Values for the two settings above can be set in the php.ini (or maybe inside your .htaccess if the webserver’s
config allows this) – usually this should be enough

If you’re running PHP as FastCGI (FCGI) you might have to adapt FcgidMaxRequestLen too, more on

Another maybe useful information if webserver is set up with suPHP enabled:

christibond said
“In .htaccess should add this line : suPHP_ConfigPath /home/<user>/etc/php.ini
This should be the path to the custom php.ini , if the account is set up with suPHP enabled.”

nginx (not officially supported) – adapting of client_max_body_size maybe needed – more information in the readme.pdf 7.b
