This is generally due to the plugin conflicting with your theme. The issue is that the plugin and you theme are both listening to the + and – button click events and they both add or subtract items from the cart. You need to disable this functionality from your theme and then everything should work as expected.

Sorry, forgot to tag the latest. Have a look now.

Would you mind sharing your code or possibly issuing a pull request on github:

Sorry about that. I’m going to have to have a look and see what the issue is. 10.0.12 fixed some issue other users were having with the inputs not responding to users typing in values. But it appears as though this fix has some unintended side effects. I’ll revert that change and push out an update for 10.0.13.

Hi Miles,
Thanks for sending through the link. Does the issue persist if you deactivate all other plugin (minus this one and WooCommerce of course). What if you change themes? Often these kinds of issue are caused by javascript conflicts with other themes or plugins.

You’ll need to copy paste the link. Looks like wordpress is changing the link to be their own site and I cannot edit it.

Sorry for the delay on this. This should be fixed in version 1.1

Can you reproduce this using the storefront theme provided by WooCommerce? If so this would help me better determine the issue.

Hi sm1975,
I won’t be able to take a look at this in the near future as my plate is pretty full with other things at the moment. If anyone else reads this who might be able to look into a fix, please issue a pull request at:
https://github.com/greatwitenorth/quantities-and-units-for-woocommerce

yeah I’m seeing something similar:

[0.0002] Uknown error: Please see returned value below
<br />
<b>Fatal error</b>:  Unknown: Cannot use output buffering in output buffering display handlers in <b>Unknown</b> on line <b>0</b><br />

Thanks for taking the initiative. Feel free to make a pull request here:

I would recommend disabling your theme’s increment buttons (this varies from easy to difficulty on most themes), then installing Quantity Increment Buttons.

Currently is does not. Might be a good feature in the future though.

you currently have javascript errors on your site. This will most likely interefere with QU:

plugins.js:72 Uncaught TypeError: Cannot read property ‘Zc’ of undefined

Fix this first and if your issue persist drop me another note.

This is most likely due to your theme already providing increment buttons and overriding QI’s functionality. Are you sure that your theme’s javascript is not overriding the increment button functionality. Most theme’s don’t implement the increment button functionality correctly. The 2 most common issues are rounding errors, and forgetting to implement the correct step values. Can you provide a link?
