Hi Gilbert,
Thanks for reaching out–I’m so sorry to hear that you’re having these issues with Community Events, but I’d love the opportunity to try and assist you here!
First things first, please make sure that you’re running the latest version of all of our plugins and that all of our plugin version numbers match. Since our plugins rely on code shared between them for a good portion of their functionality, errors can crop up when there are version discrepancies, and it does appear that some of your plugin versions are out of step.
Next, since we’ve pushed a number of updates to our plugins over the last year (and your theme and plugins have likely seen some changes, as well), I’d really like to run a quick round of conflict tests just to ensure that a conflict isn’t to blame for your problems. Would you be so kind as to take a moment to run through these steps on your site? Let us know if you’re able to do so and report back on your findings! 🙂
Thanks, and let us know if you should have any other questions!
