Piwik 2.14.0 error

I performed an automatic upgrade install of Piwik 2.14.0. Unfortunately I get the followinig error when I try to load piwik in my browser. Specifically index.php and other pages.

An exception has been thrown during the rendering of a template (“The ui asset with ‘href’ = /homepages/27/d231218971/htdocs/eyeontaiwan.com/piwik/plugins/Morpheus/stylesheets/main.less is not readable”) in “@CoreUpdater/runUpdaterAndExit_welcome.twig” at line 5.

I haven’t a clue as to what to do to fix this problem. Any help would be appreciated.
