 * On the options page, under _User(s) Browsing Site_ I’m getting this error:
 *     ```
       Warning: array_keys() [function.array-keys]: The first argument should be an array in E:\inetpub\vhosts\[sitename-excluded]\subdomains\dev\httpdocs\wp-content\plugins\wp-useronline\admin.php on line 264
   
       Warning: Invalid argument supplied for foreach() in E:\inetpub\vhosts\[sitename-excluded]\subdomains\dev\httpdocs\wp-content\plugins\wp-useronline\admin.php on line 264
       ```
   
 * Also under _User(s) Browsing Page_ this error occurs:
 *     ```
       Warning: array_keys() [function.array-keys]: The first argument should be an array in E:\inetpub\vhosts\[sitename-excluded]\subdomains\dev\httpdocs\wp-content\plugins\wp-useronline\admin.php on line 264

 * Are you also using WP-PageNavi? If yes, try installing the [development version](http://downloads.wordpress.org/plugin/wp-pagenavi.zip).

 * Hi, just want to say that you have a great plug-in. Currently, I have the same
   issue, same error message at line 264 as with richyfrost. Tried the suggested
   fix with page-navi but it didn’t work. Only had this issue since 3.0 update.

   of WP-UserOnline (2.80-alpha).
