I receive an error in my log files when I try to access the admin panel:

PHP Fatal error:  Call to a member function getResourceId() on a non-object in /var/www/magento/includes/src/Zend_Acl.php on line 1174

The admin panel stays blank. I didn't find anything about this error in Google - so it might be even something with my environment? PHP is talking about that file: http://www.magentodocs.org/ But I'm not sure whether that helps me alot :-S

Any ideas on this?

  • In your app/etc/local.xml set disable_local_modules to trueand check. If it loads fine then the issue is in one of your custom modules

The error message originates from the includes/src folder which is where Magento compiles php classes.

My current guess here is that you have the Compilation Mode enabled and installed / removed / updated an extension causing the above error.

Since your admin is not available to recover from this you need to edit includes/config.php and change




Rerun the compilation process before enabling it again. To prevent this on future occasions you need to turn off compilation mode before any updates/installs and again rerunning it.


Check if you've got a module that interferes with Magento Permissions/Roles/Users.

If you can't find anything, try to debug/output the $resource variable line 1173. There is theoretically a check before preventing it to be null that is failing. Give us what it contains.
