TEI Display error

I have installed the TEI Display plugin, but when I click on TEI in the left hand navigation, I get this error:

"exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller specified (stylesheets)' in /usr/local/data/htdocs/omeka/application/libraries/Zend/Controller/Dispatcher/Standard.php:248
Stack trace:

We have version 2.3.

That error looks like a file (/controllers/StylesheetsController.php) isn't there.

You might double-check whether that file is presents, and maybe the version of the plugin you grabbed. (I don't see an official release, but the current TeiDisplay code on github seems to work, at least for me)

The file is there and we just checked permissions were correct for it. The version of TeiDisplay I just downloaded was from github also. Any other thoughts?

My next guess is that there is a plugin somehow interfering with the correct routing. Maybe try deactivating other plugins to see if that fixes it. If so, we can then debug based on the particular plugin(s).

The versions of PHP and of Omeka that you are using might also help.
