 * I get this:
 * The plugin generated 1395 characters of unexpected output during activation. 
   If you notice “headers already sent” messages, problems with syndication feeds
   or other issues, try deactivating or removing this plugin.
 * Any idea what is going on? Thanks

 * Thanks for letting me know about this! You shouldn’t be getting this message,
   but it probably does not indicate an actual problem and it should not recur (
   except possibly at the time of version upgrades).
 * This is the first report of it from others, but there is one harmless gremlin
   that I have been chasing:
 * WP Issues CRM does create new tables in your database for efficient storage of
   constituent data. It uses the standard WordPress database upgrade routine (dbDelta
   in upgrade.php) to do that. I have myself seen on a few occasions at the time
   of version upgrades a spurious message (originating from MySQL) suggesting dup
   key error in the table creation process.
 * However, there are definitely no dup keys being created by WP Issues CRM and 
   the error is intermittent, occurring only on some upgrades/installs, so I chalk
   this up to a glitch in dbDelta — I’ve been unable to narrow it further to date.
 * If you install a [log viewer](https://wordpress.org/plugins/log-viewer/) plugin
   and [turn debug on](https://codex.wordpress.org/Debugging_in_WordPress) you can
   view the underlying error message.
 * You may see a message like the following:
    [17-Apr-2016 09:37:10 UTC] `WordPress
   database error Duplicate key name 'time_stamp' for query ALTER TABLE wp_wic_activity
   ADD KEY time_stamp ( email_batch_time_stamp ) made by require_once('wp-load.php'),
   require_once('wp-config.php'), require_once('wp-settings.php'), do_action('plugins_loaded'),
   call_user_func_array, WIC_DB_Setup::update_db_check, WIC_DB_Setup::database_setup,
   dbDelta`
 * I’d actually be very interested to confirm that that is the message you are getting.
   That’s the harmless gremlin I am aware of and will continue to pursue, but if
   you see another message, I’d be even more eager to know about it.

 * Thanks again for bringing this to my intention. I think I’ve nailed it now. There
   were some blank query requests being issued in the install process. The warning
   messages responding to those were generating the output you noticed.
 * Additionally, in the course of fixing this, I came across a bug that generated
   install errors for the reply email function in multi-site installations.
 * These bugs are all fixed in version 2.6.1 which is now live. Please do upgrade.
 * Thanks again for the feedback.
