Scripto throwing error

Hi - I'm wanting to transcribe Images using the Scripto plugin in Omeka and I'm encountering the following error: "Warning: in_array() expects parameter 2 to be array ..." My site is anpharoiste.com. Help is needed and much appreciated!

Additional information on my problem - A few days ago I installed composer, with a view of experimenting with Semantic Mediawiki.

Just now I tried uninstalling and installing Scripto plugin, and for the first time received this error:

exception 'Omeka_Plugin_Installer_Exception' with message 'Invalid MediaWiki API URL' in /home/hartal5/public_html/ioterror.com/plugins/Scripto/ScriptoPlugin.php:264

I hope this helps someone help me!

Ooops! Never mind! The error arose from something I messed up in installing SMW.
