 * After latest update (maybe it was there before I’m not sure) and while bumbling
   around to see where readygraph appears and if there ways to switch off
    I think
   on this page wp-admin/admin.php?page=s2_settings
 * I got
 * >  Warning: mysql_num_rows() expects parameter 1 to be resource, array given 
   > in …./wp-content/plugins/subscribe2/readygraph-extension.php on line 228
 * but now I cannot recreate. Thought I’d let you know anyway.
 * [https://wordpress.org/plugins/subscribe2/](https://wordpress.org/plugins/subscribe2/)
 * Also pretty please: in the changelog, please don’t just say ‘bugfix’ – put some
   detail at least. I always check to see whether it is worth the risk of upgrading
   a plugin. Inadequate detail makes me nervous.
 * Thanks

 * Hmm – it happened again on another client site.
    Upgraded to 10.20.1, clicked
   settings from plugin list clicked readgraph clicked the ‘subscrbe2’ settings ..
   it took an awful long time (what was it doing ?) and then eventually goes to 
   wp-admin/admin.php?page=s2_settings with the above error.
 * If one then goes to readygraph app again, and then click the blue menu Subscribe
   2 settings, it goes much more quickly and no error.
 * Hmm …

 * Hi there,
 * The most likely cause of the error will be the empty result of the mysql query.
   Can you tell me if the above site you are referring to has any subscribers?
