I think it is connected with the coding in the theme. I am using Woocommerce in the same manner on another author website and I am NOT getting this error. If you will see the guide that you referred me to, you will see at the bottom it references problems with the exact error code I am getting under the heading “The Additional Information Tab.”
In functions.php of the Shogun theme, you have included this snippet, which IS the additional information tab:
//// Rename product tab
function shogun_sd_wc_rename_tabs( $tabs ) {
$tabs[‘additional_information’][‘title’] = __( ‘More Information’, ‘satori’ );
return $tabs;
}
When I delete this snippet of code, then hit save, I get a 418 error.
