Bootstrap.inc error appearing on website
The problem seems to be that views_handler_filter_node_language.inc was moved from views/modules/translation to views/modules/locale. I guess you have updated the views module but not rebuilt you registry. 
You should be able to solve this by flushing the cache. Here's a issue, addressing the same problem.

Notice that whenever you update a module you should also call the update script located at example.com/update.php.

To flush the cache using drush use the following syntax: drush cc all. 

You could also try to clear the cache_bootstrap table using: 

mysql -uusername -ppassword -hhostname database -e"DELETE FROM cache_bootstrap WHERE cid='system_list';"` 


or

drush sql-query "DELETE FROM cache_bootstrap WHERE cid='system_list';"


Backup your database before trying the above

If you still have trouble, you could also try to disable the views module using something like this: 

mysql -uusername -ppassword -hhostname database -e"UPDATE system SET status='0' WHERE name='views';" 


or 

drush dis views


You might need to clear the cache as in the previous step for this to take effect.
