When we try to open previous reavision on any of the pages on this blog we have this error:
Warning: require(/var/www/domains/dbj.org/docs/dbj/wp-includes/Text/Diff/Renderer/inline.php) [function.require]: failed to open stream: Permission denied in /var/www/domains/dbj.org/docs/dbj/wp-includes/wp-diff.php on line 17 Fatal error: require() [function.require]: Failed opening required '/var/www/domains/dbj.org/docs/dbj/wp-includes/Text/Diff/Renderer/inline.php' (include_path='.:/usr/local/lib/php') in /var/www/domains/dbj.org/docs/dbj/wp-includes/wp-diff.php on line 17
Site is here http://dbj.org
This was working fine until few days ago. Also other blogs on the same machine have no problems of this (or any other) kind ?
What gives ?
