Hi there,

Apologies for the issues with the latest update. Our developers are looking into issues with the latest update and should have another software update released soon (hopefully, by the end of the day).

For the time being, you can turn off the WordPress debug mode, In your wp-config.php file search for the following line:

define(‘WP_DEBUG’, true);

And replace it with:

define(‘WP_DEBUG’, false);

That didn’t work but this did:

ini_set(‘error_reporting’, E_ALL );
define(‘WP_DEBUG’, false);
define(‘WP_DEBUG_DISPLAY’, false);

Hi there,

We’ve identified the cause of this and pushed a fix live which is version 4.10.17.p, could you please update to that version and confirm if this still happens?

If you don’t see the update available in Dashboard -> Plugins for Event Espresso then go to:

Event Espresso -> General Settings.

Don’t make any changes and just hit save to force a version check.

It should then show the update available.

My apologies for any inconvenience this may have caused.
