upgrader stuck

I have an error on the admin with the QuickPay updater – it seems to be stuck and never “clears” off the top of the page.

WooCommerce QuickPay – Data Update

The upgrader is now running. This might take a while. The notice will disappear once the upgrade is complete.

Also when I click to save something, I gt the “stay on page / leave page” notice, but when I click on “leave page” it updates as if I clicked “save”.

Do you know what’s causing this? I disabled the plugin and reacivated it but it was the same.
