FYI. The latest download on the Couch website does not include config.example.php.
Additionally - I downloaded and modified the config.example.php from the GIT repo and put it on my new site. Then navigated to the new uploaded installed 'couch' folder and got error 500:
Fatal error: Uncaught mysqli_sql_exception: Table 'mydb.mysite.couch_settings' doesn't exist in /home/mysite/public_html/couch/includes/mysql2i/mysql2i.class.php:425 Stack trace: #0 /home/mysite/public_html/couch/includes/mysql2i/mysql2i.class.php(425): mysqli_query(Object(mysqli), 'select k_value ...') #1 /home/mysite/public_html/couch/includes/mysql2i/mysql2i.func.php(247): mysql2i::mysql_query('select k_value ...', Object(mysqli)) #2 /home/mysite/public_html/couch/header.php(319): mysql_query('select k_value ...', Object(mysqli)) #3 /home/mysite/public_html/couch/index.php(11): require_once('/home/mysite...') #4 {main} thrown in /home/mysite/public_html/couch/includes/mysql2i/mysql2i.class.php on line 425
