Magento 2.2.2
What a rollercoaster this new Magento is... so I rearranged some the attributes in the Attribute Set screen for a custom attribute I was creating. I wanted to move the price, price_view and tax_class_id into the Advanced Pricing attribute group. That worked fine, no issues when saving.
Now when I go to create a product with this attribute set, everything loads fine, except I noticed there's no Price or Advanced Pricing group/accordion. In Magento 1.9.x I usually finished the price last because it takes a bit of time to work on, so I did the same here. I didn't see it anywhere, so I tried to save. I received no alerts about anything missing, and nor did the product save or refresh the page.
I figured something must be wrong with the price being in that attribute group, so I went back and put it back in the Product Details group, saved and tried to make the product again. Now this time, when selecting the product attribute set from the drop down, the page began refreshing for some time, then gave me the error:
A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later.So now, I can't make the product. The worst part is that I already did this to all the other attributes.
