Error messages began popping up

I am using v2.7 and just updated a couple of modules.

Now the blog title does not show and above teh blog< iget the following error messages:

Warning: include_once(/home/directoryname/public_html/blogs/wp-content/plugins/moonvipercmscom/) [function.include-once]: failed to open stream: Success in /home/directoryname/public_html/blogs/wp-settings.php on line 465

Warning: include_once() [function.include]: Failed opening ‘/home/directoryname/public_html/blogs/wp-content/plugins/moonvipercmscom/’ for inclusion (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/directoryname/public_html/blogs/wp-settings.php on line 465

Any ideas what the error messages mean and how I can fix this?
