This plugin is really good. WordPress has made changes to it’s core but 3CX devs are not bothered to stay up to date or at least answer our questions. The plugin is causing errors now.

The plugin brings 5.5.3 WordPress to the knees and causes lots of session errors in error logs. [20-Nov-2020 13:37:06 UTC] PHP Warning: session_start(): Cannot start session when headers already sent in /home/whmcs/public_html/ww/wp-content/plugins/3cx-webinars/includes/webinar.php on line 6

We decided for 3CX webinar plugin after an intense research on different webinar solutions like GoToWebinar and Microsoft Teams. 3CX webinars comes with a large set of professional features, is easy to use and is far ahead of Microsoft teams when it comes to webinars. Highly recommended for any 3CX users with professional ambitions. But it hasn’t been tested with latest WordPress-versions and doesn’t support latest PHP. Please test and update it, 3CX!
