Fatal Error in wordpress with evenon

Hi lately I am receiving emails fromw wordpress saying there is a fatal error with event on plugin.

I don´t know what to do. I haven´t found any specific issues but I would appreciate some help with this.

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, EventON.

First, visit your website and check for any visible issues. Next, visit the page where the error was caught (https://www.cienciaconciencia.com/wp-cron.php?doing_wp_cron=1633470250.7377939224243164062500) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

/wp-login.php?action=enter_recovery_mode&rm_token=j9ZyJlhK0ENBZHT4YtAqds&rm_key=r4EogxEAqBMPm4EwMD0HzY

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.8.1
Current theme: Thrive Theme Builder (version 3.0.2)
Current plugin: EventON (version 2.6.15)
PHP version 7.4.23

Contact the plugin author but it’s most likely the plugin is not compatible with the latest version of WordPress. You may need to downgrade
