 * While updating the Participants Database plugin on my test web server, a couple
   of database errors were displayed. I am suspecting that this is not a problem
   but wanted to check with you before I deploy to my live web server.
 *     ```
       Update Plugin
       Downloading update from https://downloads.wordpress.org/plugin/participants-database.1.8.zip…
       Unpacking the update…
       Installing the latest version…
       Removing the old version of the plugin…
       WordPress database error: [Table 'i830414wp1.wp_sm_sessions' doesn't exist]
       SELECT * FROM wp_sm_sessions WHERE session_key = '9dj9sdi1adi809g0trv6gl8h83'
       WordPress database error: [Table 'i830414wp1.wp_sm_sessions' doesn't exist]
       SHOW FULL COLUMNS FROM <code>wp_sm_sessions</code>
       Plugin reactivated successfully.
       Plugin updated successfully.
       Return to Plugins page
       ```
   
 * After the update, I executed **SHOW FULL COLUMNS FROM wp_sm_sessions** in PHPMyAdmin
   and was successful.
 *     ```
       session_id	bigint(20) unsigned		NO	UNI		auto_increment	select,insert,update,references		
       session_key	char(32)	utf8mb4_unicode_520_ci	NO	PRI			select,insert,update,references		
       session_value	longtext	utf8mb4_unicode_520_ci	NO				select,insert,update,references		
       session_expiry	bigint(20) unsigned		NO				select,insert,update,references		
       ```
