 * Hi, after installing to the latest version of redux we get the following error:
 * wp_mail has been declared by another process or plugin, so you won’t be able 
   to use SendGrid until the conflict is solved.
 * Obviously a conflict with the SendGrid plugin, resolved when redux is turned 
   off. Is there a way to fix this error?

 * Redux does not use the wp_mail API call. I just double checked the code base 
   with a full search. I can only advise you contact the author of SendGrid and 
   report it to them.

 * Shot in the dark: Try going into the `redux-core/inc/classes/class-redux-functions-
   ex.php`, comment out line 587: `require_once ABSPATH . '/wp-includes/pluggable.
   php';` and see if that solves it.

 * Hi [@doctorofcredit](https://wordpress.org/support/users/doctorofcredit/) – thanks
   for reporting this issue. We have a fix for this error and expect to update the
   plugin today (September 21, 2021).
 * In the meantime, for a temporary solution, you can take the steps mentioned by
   [@kprovance](https://wordpress.org/support/users/kprovance/) above by going to`
   redux-core/inc/classes/class-redux-functions-ex.php` and commenting out (or removing)
   line 587: `require_once ABSPATH . '/wp-includes/pluggable.php';`
 * We’ll post an update here when the update is available for download. Sorry for
   the inconvenience.
 * Chris
