Unable to Access Admin Panel

I'm using Omeka 1.1 and can't access the admin panel on my site. This is the error message that I get: Could not find file 'css/exhibits.css'!

I am, however, able to view the public version of the site.

Any tips? Thanks!

Hi amanghnani: It sounds like you activated the ExhibitBuilder plugin, but the plugin is missing some files. Navigation to 'plugins/ExhibitBuilder/views/admin/css' and see if there's an exhibits.css file in there. If not, try uploading the plugin again to your server, making sure that file is included.
