I have a message under index tables who says:
"There are 176 deferred events that will be processed shortly"
And a button:
"Force Process Queue"
What is this and what should I do?
I've not heard of these in core Magento: https://github.com/OpenMage/magento-mirror/search?utf8=%E2%9C%93&q=%22deferred+events%22&type=
Is it from a third party/custom extension that you have installed?
It could be the reason why I don't find nothing about it, I got the shop from another developer and I don't know all yet, I'll look for that
