This is just a note for myself, so please excuse the lack of polish:
If laravel is giving a “no data provided” screen, and turning on debug on does not produce any helpful results. To fix the issue replace whatever is in the .htaccess file with:
Options+FollowSymLinksRewriteEngineOnRewriteCond%{REQUEST_FILENAME}!-d RewriteCond%{REQUEST_FILENAME}!-f RewriteRule^ index.php [L]
