Jetpack CRM runs on WordPress. It is a large plugin with lots of lines of code. From time to time PHP warnings and notices may appear on your website (especially if you have got PHP error reporting set to report all messages).
If you see any PHP warnings or notices from our CRM please do tell us by submitting a ticket.

But, also, you should not let PHP notices linger and bother you.
It is best practice on a live (production) site to turn the non-destructive notices off, (as they can expose security weaknesses, generally). You can do this by making sure that error reporting is set to FALSE in your wp-config.php file, checking the following lines and setting to false (if they are true)
define('WP_DEBUG', false);
define('WP_DEBUG_LOG', false);
define('WP_DEBUG_FALSE', false);
define('WP_DEBUG_DISPLAY', false);
You can optionally make doubly by sure adding the following code (to your functions.php) or via a standalone plugin.
// Turn off all error reporting error_reporting(0);
We update the CRM regularly (almost weekly for several years) so any messages reported will be swiftly captured by our team. The above snippets will help you hide the pesky errors until we can kill them off.
