Increase maximum file size

Change the following entries in your php.ini file located in

Debian: /etc/php5/apache2/php.ini and

Windows: C:\Program Files\MindTouch\MindTouch Deki\redist\php

post_max_size = 256M
upload_max_filesize = 256M 

Once you have made the changes to the PHP.ini file, restart your web server:

Apache on Debian: /etc/init.d/apache2 restart

IIS on Windows: restart through the IIS Manager

Go into Deki Wiki control panel -> Configuration and set

files/max-file-size

to "268435456" (for 256MB)

Note: The configuration screen is introduced in MindTouch 1.8.2 (Hayes+). For previous versions, you'll need to make a direct database update into the config table and restart the application.

Windows Server 2008 - IIS7

If you're running MindTouch on Windows Server 2008 (IIS7), There is a default limit set to 30Mb by IIS 7.

To work around this problem, set in the Web.config file for the Web application to have following settings under the <configuration> section:

• Use Notepad to open the Web application Web.config file. By default, this file is in the following folder:
  Inetpub\wwwroot\wss\VirtualDirectories\VirtualDirectoryFolder
• Add the following settings under the <configuration>section of the Web.config file:
  <system.webServer>
      <security>
          <requestFiltering>
              <requestLimits maxAllowedContentLength="268435456"/>
          </requestFiltering>
      </security>
  </system.webServer>
