Recent Global Posts Not working for me.

I have put both of these files (widget-recent-global-posts.php and
post-indexer.php) in my wp-content/mu-plugins folder I added the line of code to my .htaccess file which is copied below. All I get is the error message copied below. Something is weird and I have 5 hours in on try to install this simple plugin...please help!
