I'm using "Mandigo 1.29 by t0mmmmmmm" and the custom image header reads "Unable to create directory /var/www/vhosts/catholicdestination.com/httpdocs/community/wp-content/blogs.dir/273/files/. Is its parent directory writable by the server?" whenever I try to load what I want. I've tried other themes and there is no problem, but with this one it won't load. What can I do...and I don't want to use another theme either.
