The following module is missing from the file system: (Theme name)
This is probably due to the modules changing locations since they where installed.  One way to fix this is to just edit the system table.  You can do this via Drush like this:

drush sql-cli

&gt; select * from system where name = 'bootstrap_barrio';

Verify that the path column is not correct.

&gt; update system set path='correct path here' where name = 'bootstrap_barrio';


If the path is correct, then it might be a directory rights issue.  E.g. either the module or a parent can't be read by the webserver.
