    Hi there! Thanks
   for your feedback! Sorry for delay, I was on holiday and did participate in WordCamp
   Europe in last weeeks.
 * Back to your topic:
    Are you sure, this error message comes from my plugin? What
   detailed steps led to this message?
 * What post type is it that you’re using? – From a plugin or registered via your
   child theme?
 * Thanks for any more info, as that would help me localize a bug if any in my plugin.
 * Thanks, Dave 🙂

 * Hi David. I see the same error when using Genesis Layout Extras. On the screen
   Genesis -> Layout Extras, under the Custom Post Types by Child Themes section
   I see this error:
 * Warning: call_user_func() expects parameter 1 to be a valid callback, function‘
   default’ not found or invalid function name in E:\xampp\htdocs\adamsts\wp-admin\
   includes\template.php on line 924
 * I am using the Portfolio Post Type plugin for the custom post type. That might
   be the problem…not sure. I am going to do some more research to see what I can
   find.
 * Thanks!

    Hi there! Thanks for
   your feedback and the explanation! This will be helpful for me when I will look
   into the issue.
 * I will definitely also do reasearch on it, for the meantime it is a “warning”,
   not an error, that is some difference in PHP — it definitely should not be there,
   though! 🙂
 * Thanks for reporting!

 * Any resolution on this issue?
 * Experiencing exactly same error as **adamsts** and though not using the Portfolio
   Post Type plugin, the child theme contains a manually created portfolio post 
   type.
 * Was experiencing issues with this portfolio post type and wanted to try this 
   plugin’s Minimum or Executive Archive page for Portfolio post type.
 * Thanks in advance!
