 * Hi there – looks like you have WP debugging enabled. Such warnings, although 
   not ideal, can sometimes happen without any issue to functionality. I will look
   into this, but are you experiencing any issues with the plugin? Is the Symbiostock
   > Settings page showing up?

 * FYI, this is just a strict settings warning – you should not have strict warnings
   enabled in general on a live site anyways, and you are likely to get lots of 
   irrelevant notices and warnings with a multitude of plugins with this enabled.
 * Nevertheless, this issue has been rectified and will be released as a fix with
   our next version.
 * An easy way to disable debugging is to edit your wp-config.php file and edit 
   this line:
 * define(‘WP_DEBUG’, false);
 * so it says false. If it says false already, then it is possible you have another
   line somewhere else in your code that is enabling strict debugging – this may
   be through another plugin or something else.
 * Although unlikely, let me know if you are experiencing any functionality issues
   with Symbiostock in regards to the settings page.
 * Thanks for the note!
