Hello,
I have a home page with a series of blocks that contain widgets for filtering and displaying products. They were working as expected until I took the following steps:
- Enabled flat categories and products
- Merged and minified CSS and Java
We could not fix the problem, but we did find the following:
==> var/log/system.log <==

Reviewing the exception log, this appears to relate to the /vendor/magento/module-cms/Block/Widget/Block.php

Stack trace:
There were two blocks that were not working as expected. In one, I fixed the problem because I realized that only attributed marked as visible on the front end get added to the flat table.
But the other missing block keeps producing the following (on the frontend):
We're sorry, an error has occurred while generating this email.
I have no idea why this is happening.
