I thought I'd fixed the notice when changing passwords, must've missed it. Anyway I've updated the 1.8.8 release to add this in.

On Site Notifications is a third-party plugin so I'd suggest raising an issue to the developer directly (e.g. on their GitHub repo).

Also as a reminder, you shouldn’t have notices set to display on a live site. In your php.ini set display_errors=off

Found the line in plugin and pushed a fix to the official repository. Should be fine now.
Disregard my previous comment on "qa-include/qa-base.php" @SaadH

Thank you Scott!

@gold-developer,
Today I reinstalled and activated the new (onsitenotifications) version after your recent modifications .
There is still an error message that appears after the user answers any question .
The error message is as follows :

PHP Deprecated:  strtr(): Passing null to parameter #1 ($string) of type string is deprecated in /home1/xxxxxx/public_html/xxxx/qa-plugin/q2apro-on-site-notifications-master/q2apro-onsitenotifications-event.php on line 206

@SaadH I couldn't replicate this behavior, but patched it with Scott's insight.
