System: Magento 2.1
Everything was running fine 5 minuts ago. I had 3 Products in my Catalog (all using the same Attribute Set). Then I simply deleted 2 Attributes from my (currently in use) Attribute Set via Admin Panel. Then via Magento CLI I did
indexer:reindex -> then Deleted Browser Cache.
In Browser I reloaded my webshop (everithyng looks fine). When I click on a Product -> Product Page
https://myshop.de/product1-300x200.html loads and gives
HTTP ERROR 500.
Everything else on my Webshop works fine, just all my Product Pages give me the same
HTTP ERROR 500 error.
