"-1" Showing when updating an event

Hi Matt,

Thanks so much for reaching out!

Our current best practices are to have all plugins up-to-date.  Matching the versions of plugins is not necessary or recommended anymore.

In any case, let’s try to rule out if there is some type of conflict at play.
This is usually because of:

1.    A conflict with another plugin

2.    A conflict with your WordPress theme

3.    A template customization for the Events Calendar that requires updating

When it comes to that type of issue, it is preferable to troubleshoot in a staging environment if you have one.

A first quick test is to simply temporarily revert back to a default WordPress theme such as twenty-sixteen to see if the issue persists.

The next step would be to go through our testing for conflicts procedure and let us know what you find out.

Basically the goal here is to revert back to a bare WordPress installation to see if the problem persists. It also allows us to pinpoint what the cause of the issue is.

But, before you do that, there are 2 things I would advise:

1.    Make a backup of your database

2.    Consider activating a “Maintenance Page” plugin if you are doing this on your live site (to minimize impact on your visitors)

Let me know how that goes!

Thanks,

Jaime

I solved this problem temporary with the following advice from enfold:

Error saving event – Events Calendar Pro + Event Tickets Pro

Meanwhile please update /enfold/config-templatebuilder/avia-template-builder/php/meta-box.class.php around line 262

        `check_ajax_referer( 'avia_nonce_save', 'avia-save-nonce' );`

with

        `if( false === check_ajax_referer( 'avia_nonce_save', 'avia-save-nonce', false ) )
        {
             return $data;
        }`
