Collabtive Forum

Collabtive does not restrict the size of the files you upload. However, PHP does impose limits on the size of files being uploaded. Those settings are defined in php.ini.
The number displayed as the maximum upload size in the Collabtive file upload dialog is pulled from php.ini

To increase the maximum upload-filesize you need to edit your php.ini configuration file .
You may need to ask your hosting provider how to edit php.ini.
Some hosting providers won't let you directly edit php.ini but will do it for you on request.

All filesize settings in PHP config need to be in this form: 128M.

You need to edit the following settings:

• upload_max_filesize
  The maximum size of an uploaded file. You may need to increase this. Example: 128M
• post_max_size
  Sets max size of POST data allowed. Should be larger than upload_max_filesize. Example: 130M

If that still does not help you, you may try increasing the memory limit:

• memory_limit
  Sets the amount of memory PHP may use. Example: 128M
