Upgraded to 2.0.1 and didn't notice a problem until I had to update products in my Shop (using plugin from https://shopplugin.net/) - I couldn't update certain fields in the product area & if I could, it threw up a warning.
I tracked it down to the BackUpWordpress plugin by deactivating all plugins & reactivating one by one.
It seems like a memory error in Shopp - searching for products throws up this warning:
Warning: Invalid argument supplied for foreach() in /home/hoads231/public_html/testsite/wp-content/plugins/shopp/core/model/Product.php on line 203
Going into edit a product from the search list, the page doesn't finish loading - images aren't editable and pricing area shows a spinning wheel.
Going into the product edit page via category filter, the whole page does load and I am able to make an edit and save but these lines appear:
Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/hoads231/public_html/testsite/wp-content/plugins/shopp/core/flow/Warehouse.php on line 492
Warning: join() [function.join]: Invalid arguments passed in /home/hoads231/public_html/testsite/wp-content/plugins/shopp/core/flow/Warehouse.php on line 492
When I deactivate the BackUpWordPress plugin, these issues disappear.
Any ideas? I have posted in the Shopp forum as well.
