[Plugin: Advanced Custom Fields] Fatal error: Cannot redeclare class

Until the developer fixes this, you can modify the file and wrap the class in a class_exists() condition. e.g.,

if( !class_exists( 'acf_walker_taxonomy_field_checklist' ) )
{
    class act_walker_taxonomy_field_checklist()
    {
        // ....
    }
}

Hi guys,

This looks like an error with the advanced-custom-fields-taxonomy-field-add-on plugin. I would advise leaving a support question on his / hers plugin page

Thanks

Seems the developer tried fixing it using the wrapper:

if( !class_exists( 'ACF_Walker_Taxonomy_Field_Checklist' ) ) :
....
endif;

But this still causes an error sometimes. But when I changed to the following, error doesn’t occur:

if( !class_exists( 'acf_walker_taxonomy_field_checklist' ) ) {
...
}

I tried changing if/endif to traditional {}, but I still receive the error on an irregular basis. Come on, ACF! Fix your plugin already!

@elliotcondon: This error has been reported via github and they’re pointing us back to you.

I confirm @deeve007 fix works well.

Hi @naillik

Can you post a link to the thread where they link this back to me?
I don’t see how this is an issue with ACF, the issue is with the taxonomy field add-on created by another developer.

P.S. v4.0.0 has it’s own taxonomy field built in!
