I updated the latest version of on-site-notification plugin and it works fine. But when I visited the plugin section of my website in the admin then it started to show warnings. What to do for these.

One more warning has started to show. Please help me with this.

Checking qa-page.php in v1.6.3 I see on line 734:

setcookie('qa_noticed', 1, time()+86400*3650, '/', QA_COOKIE_DOMAIN); // don't show first-time notice if a user has logged in

Line 224 also sets a cookie. Line 363 sets a header.

If this warning only appears in the admin/plugin section, you might want to modify file "q2apro-onsitenotifications-admin.php".

Because you have installed the plugin already, please try to remove the entire block of "function init_queries($tableslc) {...}" and see if the warning error still appears.

I updated the plugin on your server to the latest version, now it works without any errors.  Please keep your plugins always up-to-date. Thx, Kai

Thanks for your help, but I had uploaded the latest plugin around 10 days back but the errors were there.
It means that you have updated the plugin in the last week but I never got any notification to update the plugin in the plugin section?

I got the problem now. Thanks for your help.
