Today I am seeing this error on my admin product pages: <span style="color: #4c4d4f; font-family: Consolas, Monaco, monospace; font-size: 8.9375px; line-height: normal; white-space: pre-wrap; background-color: initial;">Warning: Missing argument 2 for wcpb_product_interface::wcpb_add_product_bundle_type() in /home/communitelligenc/public_html/wp-content/plugins/wc-product-bundles/classes/admin-form.php on line 20</span>
When I try to check out after adding to cart on products such as http://www.communitelligence.com/product/mission-possible-seven-007-tactics-that-fire-up-employee-engagement/ both the checkout and view cart links bring up timed out pages.
What do I need to do to fix this problem - urgent as all shopping is now not working.
PS: all plugins and wordpress are updated to latest.
Well the error is coming on the default 2015 theme also .
This concludes that this is not a theme issue .
