I updated the plug in today and now I am unable to make any edits to events, as soon as I choose either the save draft or publish option it returns a critical wordpress error. This is the message, any help appreciated

Hi Lisa,

How are you today?

Thank you for the information, we are looking to this on our end.

Do you know if you have any customizations to Event Espresso on your website?

Hi, and thank you. Your team is always so quick to respond, I appreciate that. We only have the Calendar plug in enabled. I do not believe any other tweaks are beign used other than a few CSS items set to display:none

Hi Lisa,

We have a suspicion that the Avada theme might be the cause of this.

Is there a chance you can change your theme on a test environment or your live site momentarily and try again?

Could you send us the zip file of your theme to

I downgraded to the previous version of event espresso and thankfully everything is back to normal. I emailed the Avada theme file as requested.

Hi there,

No issue with the theme itself, however, I assume you also have the Avada Core and Builder installed?

If so can you send me a copy of each of those over please? Same email address.
