Hi

Everything is up to date.

I tried turning off all other plugins apart from this and woocommerce but still get the error.

WP_CRON is working as auto updates have been done, so not sure what to do next?

Thanks

Peter

I have had no joy getting this to work. Tried it on a staging site without success, same error.

Any further thoughts would be appreciated.

Thanks

Peter

I received the reply below after being directed to another support group.

Is there any point in trying the Elite Version?

Hi Peter!
The Australian site will not run Product Feed Pro, givng a critical error when creating the feed.
Because of differences in databases -- not only i.e. versioning, but things as fundamental as naming conventions used in settings -- site migration can sometimes be devilishly tricky in unexpected ways.
Alas, we can only help with plugins we make and/or sell at WooCommerce.com, so I don't think we'll be able to shed much light on this problem with Product Feed Pro.
What I will say is, since WooCommerce is open source, you can at least find and examine the lines that the error message refers to.
For example, /woocommerce/includes/wc-product-functions.php:1083 seems to be concerned with setting a variable called $line_price: $line_price = $price * $qty;
Although I'm not really a coder, the phrase "unsupported operand type" often means an issue caused by mixing strings and integers. That is, the code is attempting a mathematical operation on a non-numeric string.
I have installed a clean version of woocommerce on the Australian server and Product feed Pro works on it.
This sounds hopeful. If you then gradually reintroduce the other plugins, theme etc, does it continue to work? That would be my advice if the developers of the Product Feed Pro plugin aren't able to assist.
I hope that's of some use; I regret that this is outside the scope of our support!
Best,
Damien -- Woo Support
