I wrote this list before on this issue: http://drupal.org/node/166557; but, received no response. Decided to re-pose the question. The problem is that I'm getting the "access denied" error on file upload even though the file is uploaded. This is because user_access('upload files') is failing for a user who, in fact, has this permission in this particular group. I did the following: 1. Modified user_access() function to NOT cache the $perm permissions. 2. Deleted records from cache_menu. I don't know which (if not both) of the above did the trick, but it resolved the issue. That means (I think) it's a cache problem. I know I can use cache_clear_all() to delete items from cache_menu. However, I would like know if it's possible to delete/modify the static $perm variable that is set in the user_access() function OUTSIDE of that function? That is: The user_access() function sets a static variable $perm = array(). Permissions are cached in this variable. Can I create a function in my module that can update the $perm variable that is set in the user_access() function of the node.module? Thanks for any assistance. -ron -- Ron Parker Software Creations http://www.scbbs.com Self-Administration Web Site http://saw.scbbs.com SDSS Subscription Mgmt Service http://sdss.scbbs.com Central Ave Dance Ensemble http://www.centralavedance.com R & B Salsa http://www.randbsalsa.com
