I had this issue recently on PyCharm 2020.3.3 Community Edition.
What I've found is in the top right corner of the editor there is a Reader Mode button.
If you click it you turn the Reader Mode off and then you can see your errors.
You can re-enable it by clicking the book icon

In my case, I had some ticks disabled in the Python Inspections menu in Settings > Editor > Inspections > Python. I have ticked everything and applied, and now it is working.
I don't really understand why this happened as the problem arose from one day to another. I had even re-installed the whole PyCharm, trying older versions, and deleted the .pycharm configuration folder from home.

I had the same issue with PyCharm Community Edition, v.2016.3.2. To fix,
go to Preferences... from the PyCharm menu, and open Editor/Colors & Fonts/General
Now go to Errors and Warnings/Error under your current schema.
I also had to set my Project Interpreter under Preferences/Project:<name>/Project Interpreter.
See screenshot.

None of the previous answers worked for me when I ran into this issue, but I was able to fix it by doing a hard reset on my PyCharm settings:
From the main menu, select File | Manage IDE Settings | Restore Default Settings.
You will lose all your custom settings this way of course, but this was the only thing that worked for me.

I have tried many things, but only Invalidate Caches did the trick, after that I could hover the green arrow (top right side) and change Highlight to All Problems
