 * When activating the plugin, I get the following error:
 * Notice: has_cap was called with an argument that is deprecated since version 
   2.0! Usage of user levels by plugins and themes is deprecated. Use roles and 
   capabilities instead. in /web/sites/depts/150/web/memories/wp-includes/functions.

 * Since the file path you are providing is hinting that the error was thrown within
   the wordpress core, I’ll need to know what version of wordpress you are using.
   It doesn’t mean I am not doing that causes the error in a special environment,
   but I was unable to reproduce this issue with WordPress 2.9.2 through to 3.0.4.
 * Any additional information such as WordPress version and PHP version would be
   appreciated.
 * Thanks!
