When I click on "Themes" in admin panel, I get the error below

An error has occurred in Omeka. To track the contents of this error, please enable error logging.

Warning: file_put_contents() [function.file-put-contents]: Filename cannot be empty in /home/musla/public_html/rccgoneplace.com/resource/application/libraries/Omeka/Logger.php on line 68

Please Help.

What version of Omeka are you running?

I realize that this post is quite dated, but I thought I would comment, as I am having this same problem. I'm running OKAPI 0.9.2. Any thoughts?
