I am working on a site in which it was perfectly, but now its given this error
Fatal error: require_once(): Failed opening required '/var/www/.../includes/sites/all/modules/context/plugins/context_condition_sitewide.inc' (include_path='.:') in /var/www/.../includes/bootstrap.inc on line 3139.
Here we can see the path is changed .../includes/sites/.....
where as the "include" and "sites" are on root folder.
So please guide me that how to solve this issue.
