# Activating Development Mode for Pro version

 * When I use my license to try and test the plugin on the development server, I
   get the following message:
 * _License key is correct but already in use on another site. See the FAQ for how
   to enable Pro version in development mode. _
 * However, when I look in the FAQs, there is nothing there that details how to 
   do that.
 * Does anyone have any ideas?
 * Thanks!

 * Ssshhh! Save yourself the trouble and just add the following into your **wp-config.
   php** file:
 *     ```
       define('W3TC_PRO',true);
       define('W3TC_ENTERPRISE',true);
       ```
   
 * Now you have the Pro and Enterprise editions for free and working forever. Bye
   bye license key issue.
 * I mention this because as you will find out soon enough (if u havent already)
   the author’s support for this plugin is absolutely non-existent. Just roam this
   support thread of angry folks. That’s why it is always advised not to pay for
   it.
    A forked version was made that fixes 50+ bugs still present, that a lot 
   of us here are currently using instead.

 * Thank you. That worked. I may need to work with the forked version as well. I
   appreciate the heads up.
