 * I installed the plugin, and did the initial settings before getting to choose
   the addons stage the following error was displayed:
 * Warning: call_user_func () [function.call-user-func]: First argument is expected
   to be a valid callback in / home/bolan138/public_html/wp-includes/functions.php
   on line 2035
 * Warning: include (/ home/bolan138/public_html/wp-content/plugins/mycred) [function.
   include]: failed to open stream: No such device in / home/bolan138/public_html/
   wp-admin/admin.php Online 167
 * Warning: include () [function.include]:. Failed opening ‘/ home/bolan138/public_html/
   wp-content/plugins/mycred’ for inclusion (include_path = ‘:/ usr / lib / php :/
   usr / local / lib / php ‘) in / home/bolan138/public_html/wp-admin/admin.php 
   on line 167
 * And myCRED not appear in the wordpress admin menu and also I can no longer see
   the initial settings.
 * Is there any way to solve this?

 * Hi.
 * Do you have a mycred folder in your plugins directory: wp-content/plugins/?
    
   What is your PHP version?

 * Yes, myCRED folder is in the plugins directory (wp-content/plugins/mycred) and
   the PHP version is 5.2.17

 * As stated in the [forum information post](http://wordpress.org/support/topic/mycred-133-update?replies=1),
   1.3.3 does not support PHP 5.2.17 and should not be used. I am working on a fix
   in 1.3.3.1 which will be out in a day or two.

 * No problem. You can download 1.3.3.1 from the “Developers” tab here on wp.org
 * Let me know if you require any further assistance.
