Menu not updated after role purchase after a user purchases a certain role (i use UC and a rule to do so) the main menu is not updated automatically. The user had access to everything that belongs to the new role, but the menu only gets updated when i manually clear the cache on the site. 
In searching for a solution i found this has to do with menu caching. 
I don't use drush or devel and need a solution that suits a production site. Is it best to completely disable menu caching? And how do i do that? Is there a module for that? 
Thanx,
Cas
You cannot disable menu cache - if you could, Drupal would need to scan all modules on every request and it would kill your site. You can use Cache Actions:


  It currently provides actions for:
  
  
  Clearing Drupal cache bins
  Clearing CSS/JS cache
  Clearing The cache of specific views
  Clearing The cache of specific panel pages
  Clearing The cache of specific mini panels
  


Just clear menu cache in the same rule you use to add a role to your user. After adding that role, of course.
