Cannot Update Product Quantity after Update

Hi @dansperfect,

Kindly check if the issue is caused by a conflict with your theme or with another plugin.
?
The best way to determine this is to:

• Temporarily switch your theme to Storefront
• Disable all plugins except for WooCommerce
• Check if the issue is still there

?
If you don’t see the issue, then you know that it was caused by the plugins and/or theme you deactivated. To figure out which plugin/theme is causing the problem, reactivate your other plugins one by one, checking whether the issue returns after each activation, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.

Let us know how it goes.

This is definitely a Woocommerce problem, which they have yet to admit to. Lots of people having this same issue (including me). I have found a few posts with workarounds but hopefully woocommerce take responsibility and fix it properly soon.

I’m yet to try these as I only just found them but thought I’d share so you can get sorted asap.

Here is the thread with some ways to at least make it temporarily usable:
