I've built my site locally, and just pushed it onto a dev server for testing, but I'm getting the following error on single product pages:
'Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /home/richeflo/public_html/dev/wp-includes/plugin.php on line 406'
Here is a link to the site: http://dev.richeflowers.com/product/ines/
I have a couple of WooCommerce extensions running, but have disabled them all and still get the error. I can't see what is causing this. Any help is very much appreciated!
