 * Since the 3.2.3 update, there is an issue with the SendGrid plugin, the error
   is:
 * `SendGrid: wp_mail has been declared by another process or plugin, so you won't
   be able to use SendGrid until the conflict is solved.`
 * Hope you can solve this asap.

 * Looks like they have quite a serious XSS security issue going on, bad form to
   mask it as a PHP “compatibility” tweak.

 * Don’t see anything that should have made wp_mail freak out though.

 * The support and Dev teams are currently taking a look at the issue and we should
   have a response / solution shortly.
 * [@khromov](https://wordpress.org/support/users/khromov/) The update for the security
   issue is listed as “Preventative: Security improvements” and admittedly was left
   off on the initial submit. The issue was noticed within an hour of release and
   the Changelog was updated before your report [https://plugins.trac.wordpress.org/changeset/1549802/mainwp-child](https://plugins.trac.wordpress.org/changeset/1549802/mainwp-child).
   At the same time we also put a notice in the [MainWP Usergroup](https://www.facebook.com/groups/MainWPUsers/permalink/1170498299713509/)
   and sent out an email to all our subscribers.
 * I appreciate you keeping us on our toes.

 * I have version 3.3.1 and I still get errors while using the SendGrid plugin
 * SendGrid: wp_mail has been declared by another process or plugin, so you won’t
   be able to use SendGrid until the conflict is solved.
