 * Hello,
    Love your plugin and have begun to use it on a number of products on 
   a site I’m working on. Unfortunately, it started throwing this error today which
   is also ruining the appearance of the website (by pushing all content down to
   make room for the error message).
 * Warning: array_merge(): Argument #2 is not an array in /home/sitedirectory/public_html/
   wp-content/plugins/woocommerce-product-addon/classes/ppom.class.php on line 169
 *  I’ve disabled all other plugins and used other themes yet the issue persists.
   If you could let me know what I might be able to do to fix this, I would appreciate
   it.
 * Thanks,
    TAB

 * To be more specific, I’ve switched to Twenty Nineteen which doesn’t have any 
   WooCommerce template overrides and am only running the plugins WooCommerce & 
   WooCommerce Product Addons. The error persists.

 * OK, well, I found out it was my own fault. I had created a conditional PPOM Meta
   for a product, applied it and added it to the cart for testing. I later deleted
   this meta and went with another method, but left the product in the cart. When
   I deleted the product with missing meta applied, the error went away. Sorry to
   have bothered you but hopefully this will help someone else who runs into the
   same issue.
