Error can some one please help

UsersManager.getTokenAuth is expecting a MD5-hashed password (32 chars long string). Please call the md5() function on the password before calling this method.

Does anyone know how to fix this it happened after a server migration

I got that issue fix and now I get this

#0 /home/superher/public_html/piwik/piwik/plugins/UsersManager/API.php(251): Piwik_UsersManager_API->checkUserExists(‘anonymous’)
#1 /home/superher/public_html/piwik/piwik/plugins/UsersManager/Controller.php(205): Piwik_UsersManager_API->getSitesAccessFromUser(‘anonymous’)
#2 /home/superher/public_html/piwik/piwik/plugins/UsersManager/Controller.php(175): Piwik_UsersManager_Controller->initViewAnonymousUserSettings(Object(Piwik_View))
#3 [internal function]: Piwik_UsersManager_Controller->userSettings()
#4 /home/superher/public_html/piwik/piwik/core/FrontController.php(138): call_user_func_array(Array, Array)
#5 /home/superher/public_html/piwik/piwik/index.php(53): Piwik_FrontController->dispatch()
#6 {main}

where did you get the error? do you use custom code or plugins?
