2.1.0 - New / Edit Product interface is missing product info section (name, sku, enabled, etc.)

[itdint]

When clicking on products > catalog > and new / or edit product, the interface is broken. I can't find a good reference of what the 2.1 product entry interface looks like - i know the sidebar went away, but it appears to be missing the first accordion section that has name, sku, enabled, etc. You cannot add a new product because these fields do not exist and it will not pass verification. I have searched the issues pages and in general for several days and have not found this particular issue addressed.

Preconditions

1. Magento 2.1.0
2. Server is Ubuntu 14.04, nginx 1.4.6 php 7.0.9, MySQL 5.0.12
3. Site was installed via composer - upgraded from 2.0.4, have applied all patches.
4. I am running a custom front-end theme (Porto 2.3.2) however, it does not alter any adminhtml files.
5. I am using the nginx.conf exactly as it was provided in the magento 2.1 downloaded release.
6. php env vars have been updated - memory_limit is 1048M just to make sure that isn't an issue.

Steps to reproduce

1. I upgraded via commandline / composer from 2.0.4 to 2.1.0. Nothing out of the ordinary.
2. Error happens regardless of deployment mode, or whether I re-compile, or re-deploy static content.
3. So far - all other admin areas, config panels, seem to work correctly.

Expected result

1. I should be able to set the name, sku, etc. of a product. As of now I can't add new products, or successfully edit existing products.

Actual result

1. Logs - I have scanned nginx logs, syslogs, magento's debug and exception logs - no errors are present that I can find.
2. I have monitored the page in the inspector console - there are no indications of missing js files or any js errors. No console output at all.

Hi, can you give us the list on enabled modules? And more importantly, have you applied the patch provided by Porto for magento 2.1?
You should have a Porto Theme(Magento 2.1 Patch).zip file.

Well - it may not matter. I think whatever issue this is, it has to do with the upgrade from 2.0.4 to 2.1.0. I created a clean 2.1.0 install on the same server - thinking I could use it for code comparison, and the clean install works perfectly. I installed the same porto theme, patches, etc.. and it still worked - so I just moved the catalog from the broken store to the new one. The strange thing is there was never any error - logged or in the console. Made it really hard to troubleshoot.

I'll go ahead and close this since i found a workaround.
